This meta (and possibly the main site) had quite a lot of links to the meta.MO site, which is now replaced by a modern SE site. The previous meta was moved to http://tea.mathoverflow.net.

Is it possible somehow to edit all the links (here and on the main) to meta.MO to point to tea.MO instead?

Edit: Seeing how there is a new meta.MO, and new links will be flowing in soon, it might be worth getting to this issue sooner rather than later?

• Is this in response to this comment? – Willie Wong Jun 25 '13 at 11:03
• @Willie: More or less. It occurred to me that this is an issue when I was looking for something related to MO on this meta and found links to meta.MO which are now rotten. – Asaf Karagila Jun 25 '13 at 11:07
• s{meta.mathoverflow.net/discussion}{tea.mathoverflow.net/discussion}/g -- to make the proposal more concrete :). This does not mess with the links to the new meta.MO. – ˈjuː.zɚ79365 Jun 28 '13 at 15:25
• @ˈjuː.zɚ79365: True, but still no reason to wait much longer... – Asaf Karagila Jun 28 '13 at 19:27
• Can we either (1) get this done already; or (2) have an explanation of why (1) is not possible? – Lord_Farin Jun 28 '13 at 22:34
• @Lord_Farin: Or (3) get an explanation why (1) must be delayed, but will be done soon. – Asaf Karagila Jun 28 '13 at 22:37
• Redirecting meta.mathoverflow.net/discussion/.* to tea.mathoverflow.net is a better approach, as it fixes links on other sites too, and it's probably easier to implement. – Ayman Hourieh Jun 28 '13 at 23:46
• @AymanHourieh Good idea! SE webserver logs should have some 404s from old links to meta.MO already. To better communicate the point to whoever reads the logs, I searched for "meta.MO" here and clicked on outdated links to add a few more 404s. – ˈjuː.zɚ79365 Jun 29 '13 at 1:15

Since there weren't that many links, I've gone through them manually and fixed what the searches turned up here on meta (flooding the front page, but I thought that would be less annoying than spreading the edit operation over weeks doing two a day ;).

On main, there are fewer links, those will be dealt with manually too.

• What about comments? – Asaf Karagila Jan 28 '15 at 19:54
• Well, those were the larger number. SEDE returned about 50 here, and about 20 on main. It should return only the ones that contain the string meta.mathoverflow.net/discussion in backticks from the comments here after the next data update (Sunday morning, iirc). But I may have missed one or two, or the query missed some. Anyway, I've changed the links in a lot of comments. (Also on main, now.) – Daniel Fischer Jan 28 '15 at 19:58
• Awesome. You're true to the Moderator brand that is "Fischer". – Asaf Karagila Jan 28 '15 at 21:14
• @Daniel Fischer: there are 19 questions you have edited on the front page of meta.MSE at the moment! I would have found it less annoying to have them done a few at a time. – Carl Mummert Jan 29 '15 at 0:27

I'm not exactly sure what you are proposing. As of this writing, there are just 10 posts that link to tea.mathoverflow.net.* There 6 on the main site. All but one of those are copies of this meta answer. As far as I can tell, all of these links are still active. While there has been some recent discussion of moving to the Discourse platform, I haven't heard anyone propose the pages on http://tea.mathoverflow.net/ be removed.

If, by chance, those links break, we can look into fixing them.

* Including this question. 11 after this answer.

• Links to tea.mathoverflow.net are not a problem. It's the links to meta.mathoverflow.net/discussion/ that are broken. They are found here on meta, though since there are only 22 of them, I don't know why we just didn't edit them ourselves. – user147263 Jan 27 '15 at 23:48
• @Fundamental: Ah. Now I understand. Yes, it makes a lot more sense to edit them manually if there are that few. – Jon Ericson Jan 27 '15 at 23:51
• @Fundamental: What about the ones in the comments? (Which are the ones that cannot be edited manually by common users...) – Asaf Karagila Jan 28 '15 at 5:20
• @AsafKaragila If there are any worth keeping, mod-flag to edit; otherwise obsolete. – user147263 Jan 28 '15 at 5:21
• @Fundamental: How do you propose to find these links? I propose "someone" to write a data.SE query to find them comments! :-) – Asaf Karagila Jan 28 '15 at 5:22
• @AsafKaragila Here it is... one of those comments is yours. – user147263 Jan 28 '15 at 5:39
• @AsafKaragila I posted the query in Mods' office. – user147263 Jan 28 '15 at 5:48
• @Fundamental: And there are 19 more comments on main. Isn't it just easier to run a quick perl script s/meta.mathoverflow.net\/discussion/tea.mathoverflow.net\/discussion or something like that and save the trouble of flagging nearly 70 comments then have the mods edit and/or delete these comments? – Asaf Karagila Jan 28 '15 at 5:48
• @AsafKaragila Those on main can be summarily deleted. – user147263 Jan 28 '15 at 5:52
• @Fundamental: We're out of season for a summerly deletion. :-P – Asaf Karagila Jan 28 '15 at 6:08
• @AsafKaragila: It probably would be easier to run a script. (Actually it would be SQL update.) The trouble is I'd need to convince someone who has write access to the data to do it. ;-) – Jon Ericson Jan 28 '15 at 16:23
• @AsafKaragila It's summer where Pedro Tamaroff lives, so... – user147263 Jan 28 '15 at 16:30
• This thread will become incomprehensible after/if the script is run. – Najib Idrissi Jan 28 '15 at 16:53
• @JonEricson Since there aren't so many links, it's doable by hand, I've already started updating the links. If one had a redirect meta.mathoverflow.net/discussion/xyz -> tea.mathoverflow.net/discussion/xyz, that would also fix links from elsewhere, and that could be useful. But letting everybody fix their own works too. – Daniel Fischer Jan 28 '15 at 18:52
