Also known as the happiest place on the website! Use this thread to congratulate MSE users that you feel have reached a significant milestone on the website, or to congratulate the website itself, if you are so inclined. Frequent themes:

• A user reaches an integral multiple of 100,000 reputation points;
• The website reaches a number of questions/answers/users with a lot of zeroes at the end;
• [to be expanded]...

To reiterate, this thread should be a happy place. No mean comments directed at the congratulated people, please.

Some context: the celebration tag has been growing here on meta. Meanwhile, some people think these posts should be regrouped into a single thread, and these threads have become less popular than before. Recently, Alexander Gruber made a suggestion that was well received: +38/-5. This is an attempt to implement this idea. The idea of editing the title with every new post was met with some resistance, but this can be implemented later if need be.

Meanwhile, the History of MSE thread seems to be for significant milestones: there can only be one instance of a user reaching 100k for the first time. This prevents congratulating users on an individual basis.

• As for why I went ahead and created the thread: there's sometimes a bit of inertia on this website. After a month and a half and without huge complaints against Alexander Gruber's idea, I thought it was time to try it out. – Najib Idrissi Jan 7 '15 at 16:55
• Voting on a discussion does not necessarily mean dis/agreement with any idea presented in OP. (It was likely still a good idea to create the thread.) – quid Jan 7 '15 at 17:06

• What's with all the downvotes on answers in this thread?? What do people think they are accomplishing?? – 6005 Mar 12 '15 at 8:20
• No idea @C-S. I once tried to explain that one goal of creating a big thread was so that people could downvote the big thread without downvoting individual users' congratulations (which could feel more like a personal attack), but the discussion was derailed by a troll and subsequently deleted. – Najib Idrissi Mar 12 '15 at 9:24
• Has anyone compiled records of the "best" question posers, as opposed to the best question answerers? Would be more difficult to measure... – Joseph O'Rourke Oct 8 '15 at 23:28

Congratulations to Qiaochu Yuan for being the first user to reach 1,000 (non-unique) badges, including 15 gold and 469 Nice Answers!

Congratulations Daniel Fischer for getting into the 100k club. Your clear explanations and helpful hints combined with your patient mentoring does not go unnoticed in the math chatroom. Also this accomplishment has not been mentioned.

• congratulations =) ! – user153330 Jan 16 '15 at 13:26

User Did has just hit 200K rep today, and the number of 200K+ users on Math S.E. is now three.

Congratulations for your fantastic achievement Did! Your dedication, enthusiasm, and insight are really inspiring. You worked hard, you deserve it, and now you have got it! Please accept our congratulations on this wonderful recognition of your merits. I wish you many years of great achievements! Keep up the good work!

Congratulations to me, the first ever recipient of the highly-coveted big-list bronze tag badge. This goes on my CV, for sure.

EDIT–––Even more congratulations to me, for achieving a reputation of exactly 123,456. Just enjoying it while it lasts.

• I have to thank all the little people who made my amazing achievement possible. – Gerry Myerson Sep 11 '15 at 5:19
• That's pretty crazy. – Stella Biderman Feb 1 '16 at 5:22
• And as quickly as it arrived, it was gone again. You have my condolences. – pjs36 May 9 '16 at 14:19
• It's probably just me, but I habitually misread those tag badges as concerning non-commutative wiki answers. – hardmath May 9 '16 at 15:24
• Out of idle curiosity, I did a histogram for the ones digit from the reputations of the $36$ highest-reputation people. Listing the digts from $0$ to $9$, it's $(7,2,5,4,2,0,8,3,3,2)$. Interesting that $6$ and $0$ are most common, while $5$ is absent. – Barry Cipra May 9 '16 at 15:51
• IMHO, 123456 isn't that interesting as a number, wait until 196883 when you faithfully become a Monster ;-) – achille hui May 9 '16 at 16:45

Congratulations to Jack D'Aurizio on reaching 100k reputation.

He has made several great answers with often inspiring, creative and elegant solutions.

• Congrats on achieving this milestone for which you obviously worked so hard. Your numerous insightful solutions have been a benefit to this site. – Ron Gordon Oct 3 '15 at 17:26
• @RonGordon: I am just waiting for you to achieve the same goal ;) – Jack D'Aurizio Oct 5 '15 at 1:04
• @JackD'Aurizio Your answers are always pretty. You have a great gift for problem solving. – user223391 Oct 5 '15 at 3:47

Congratulations to Qiaochu Yuan for reaching 200k reputation today!

Qiaochu is already a great contributor to the site in terms of giving answers, but let's not forget the fact that he has also served the site as one of the moderators for over 2.5 years.

Congratulations to Henning Makholm on reaching $100$K on $5$ March $2015$, bringing the number of $100$K+ users to a full score; not bad for someone who describes ‘[r]eal mathematics’ as ‘more of hobby’!

• I was just going to post such a thread. Glad you beat me to it, @Brian. More to the point, congratulations, Henning!! I always enjoy reading both your answers and your comments. – amWhy Mar 6 '15 at 14:01
• Thanks, Brian, @amWhy. It would have been more fun to clear the threshold back when it meant something, but eh. – hmakholm left over Monica Mar 7 '15 at 19:40

Congratulations to Ron Gordon for his glorious achievement: reputation over $100$K.

This man is a bless for us all: I learned so much by studying his answers in complex analysis, I will be grateful to him my whole life. And that is just a tiny part of his merits.

• Jack, words fail. Thank you. We learn from each other - I have learned from you and many others on this site. It is a truly awesome thing we have here. – Ron Gordon Jan 31 '16 at 1:04

Congratulations to Georges Elencwajg for surpassing 100,000 reputation on this final day of 2016! Georges's answers in algebra and geometry are an amazing resource for a multitude of users. His cordial and inviting demeanor makes even the most technical of his posts a pleasure to read.

Félicitations, et bonne année 2017!

• Merci, SpamIAm, et tous mes voeux de bonheur à vous, à ceux que vous aimez et à ceux qui vous aiment. – Georges Elencwajg Dec 31 '16 at 22:00
• For obvious reasons it isn't I who upvoted :-) – Georges Elencwajg Jan 1 '17 at 8:54
• @GeorgesElancwajg I certainly did! Here's to the next 100,000 internet points' worth of wisdom, cheers! :) – pjs36 Jan 1 '17 at 19:07

Congratulations, rschwieb, on reaching 100k reputation points!

Keep up the good work!

• Hey thanks! Seeing the site over the past 6+ years, I think we're doing a good job, and I hope I can continue to help make the community a great place. – rschwieb Aug 22 '18 at 20:20

Congratulations to Brian M. Scott, who reached 300K reputation as second user today! Also, it turns out it is exactly four years since he posted his first answer. My guess is that he planned on this.

Thank you for your great work for the community!

• and recently the first to 500k. – qwr Aug 29 at 9:23

Congratulations to Mark Viola, the artist formerly known as Dr.MV, for reaching 100,000 reputation!

I think I speak for many here when I say that we admire his tireless and constant striving to "provide the best answer [he] can" (as his frequent comment on his own answers says). Even now, over two years after joining, he is consistently a top contributor, and I think it is only right that we acknowledge explicitly the considerable contribution he has made to this community already, and, we may selfishly hope, for a long time to come.

In the words of Geoffrey Boycott, now 'e's got an undred he's got te knuckle down fer a really big score!

• Congrats Mark!! – Ron Gordon May 23 '17 at 22:53
• Hey Mark, also congrats from my side! You are one of the best here on mse! – tired May 31 '17 at 19:04
• I am late to the party and quite ashamed of that, but Chappers' words do the job nicely. I agree with tired, too: Mark is simply great. – Jack D'Aurizio Jun 1 '17 at 1:45

Congratulations to Olivier Oloa for reaching 100K. I share many interests with Olivier and I learned very much from his always elegant and inspiring solutions. I wish him a pleasant stay and to reach many other glorious achievements, for the benefit of our whole community.

Congratulations, Michael Hardy for topping $100K$ on 2/11/2015! Passing $100K$ in one's journey at MSE is a significant achievement that shouldn't ever be minimized.

You've been a steadfast contributor at MSE: thank you for your countless answers AND thank you for all the time you spend editing and improving both questions and answers.

• His efforts related to editing got mentioned in chat when he reached 10k edits last november; now already at more than 11k. – quid Feb 12 '15 at 16:30
• Thank you. (I hadn't known this posting was here or that this thread exists until a moment ago.) ${}\qquad{}$ – Michael Hardy Oct 3 '15 at 20:03

Congratulations to Claude Leibovici who topped $100K$ yesterday!

You have been supplying wonderful answers over here, so congrats on all the hard work taken to build these reputation points and may you continue to give good answers, sir!

• My warm congratulations Claude for your first 100K! Wishing you a very pleasant end of year and continuation here. All the best, – Raymond Manzoni Dec 21 '17 at 14:19
• I do not want to make one more redundant post, so I'll mention at least in comments that also Jyrki Lahtonen reached 100k this month. – Martin Sleziak Dec 22 '17 at 4:04
• @Claude Congratulations! Knowing your profile, let me tell you that you are, among other things, a model of courage for many of us. – Olivier Oloa Dec 23 '17 at 9:00
• @MartinSleziak I don’t see the harm in redundancy in this thread — Jyrki has been an excellent moderator and contributor, IMO. Plus it seems ideal that comments to this answer should really be focused on Claude (by whom I have also been very impressed!) – pjs36 Dec 23 '17 at 14:35
• @pjs36 Feel free to post a separate answer for Jyrki. (If you feel like it, you can also mention that it has been three years since he became a mod.) I tried to respect the fact that many users are against posting congratulatory posts on meta - but since these two users reached 100k almost simultaneously, I was unable to resist and posted at least a comment. (Alternatively, if you think my comment here is unsuitable, you can flag it and ask moderators to remove the comment.) – Martin Sleziak Dec 23 '17 at 14:39

Congratulations to Eric Wofsey for reaching 100K!

Eric, thank you so much for all of your awesome proofs and counterexamples. Seeing a comment by Eric on a tough (imho) topology problem lets me go to sleep easier knowing the problem is in good hands.

Congratulations, to Sami Ben Romdhane who has topped $100$K today!

You've been a great contributor here at MSE, so let us take a moment to recognize your hard-earned achievement and cheer you on as you continue to do so!

Keep up the good work, Sami!

• yeah! congratulations to one of the great contributors on M.SE ! =) – user153330 Jan 16 '15 at 13:25
• I was sad to see today that Sami's account is suspended. He's been a great contributor, as amWhy says. – Simon S Apr 29 '15 at 15:10
• I was even more sad by noticing that he left MSE soon after the suspension was revoked. Goodbye, Sami. – Jack D'Aurizio Oct 1 '15 at 19:00

Congratulations Arthur, for getting into the 100k club. Not bad for someone who describes himself as an “hopeful mathematics student with some competition level problem solving experience”.

Congratulations Pedro Tamaroff for getting into the 100K club.
