There is a very simple reason why we should not encourage posting about open problems by plain amateurs. If we allow just one, to be consistent we would need to allow a hundred. With the recent popularization (yet again) of the Collatz conjecture, we are already seeing a significant number of posts by people who do not even know what a mathematical argument ...

If a question gets undeleted, the user who posted gets no notification about that undeletion. But you also get no notification if an answer of yours gets deleted. The only thing that happens (as you were told in the comments) is that that deletion or undeletion may cause a change in your reputation. Whether a user should get a notification under those ...

No. Any comment flag is resolved as helpful when a comment is deleted, unless the flag has aged away or the moderators declined the flag prior to deleting the comment. If you feel that something might be still off, you can find the post in your flagging history and raise a moderator flag alerting us to a problematic comment.

Since it's one way of describing a root of a polynomial with Maple's RootOf (see the documentation, for instance RootOf(x^2-2,1-I..2+I) is $\sqrt2$), I would say the answer is not inherently bad. However, it's a very late answer (the question was asked more than three years ago), which means it will likely be useless to the OP. To make it useful to the ...

Yes, and your example shows why. Most deletions of answers are not motivated by the mathematical content of the post, yet instead by formal reasons, e.g., the answer-post is asks a new question, and thus should be a new question-post or maybe a comment; the answer-post tries to engage with other users, and should be a comment, instead; the answer-post ...

First of all I advise you until the question is total spam anyone should not delete their question if some person has answered that because then you are disrespecting the other people answer. Also do remember you can't delete a question if you have accepted one of the answers. So you can't delete these answers. Instead of consider deletion try to focus on ...

Both the questions referenced by you above have been deleted following their linking to the CURED chatroom (I did the linking, so I'll answer this as well). But I'll say a few more things. If you have a doubt on the quality of a particular question , then you can take a look at the current close vote and up/downvote count of the question, and once again ...

I saw this Meta question of yours, and happen to be the second undelete-voter. Let me explain why I voted to undelete. I did not see any indication that your answer was flawed, and I supposed that you would have stated it somewhere if it was. From what you say here, it seems that my guess is correct. Thus I think it is better to leave your answer undeleted. ...

In fact, in the blue box, the users are arranged in ascending order of their user ID. To verify this, one might move the mouse over the link of each user. That would display a tooltip text showing the URL of the user profile. The user ID appears in the middle of the URL.

The answer was flagged as low-quality, and I encountered it in the low-quality review queue. My initial impression of the answer was that (a) it was likely far too terse to completely answer the question and (b) didn't really address the question of uniqueness at all. My reading of the question was that the issue of uniqueness was somewhat central, and ...

I'm somewhat sympathetic to your surprise, first at having your Question marked as a duplicate of an apparently different problem (in this case by a "golden hammer wielding" single user), and then at having your Question deleted. I've upvoted your meta Question accordingly. There is a commonality of technique in solving your problem and the one it ...

From the FAQ What are the reputation requirements for privileges on sites, and how do they differ per site? at Meta Stack Exchange (specifically, see the section titled "Privileges not tied to a specific threshold"): For every 1,000 reputation after gaining the moderator-tools privilege, you gain another delete vote. (Delete votes are capped at 30 ...

Since your first question already has an answer, leave it as is and ask a new one. The first question, even though it's not what you intended, already became a piece of knowledge in Q&A style. Maybe it can benefit others. Maybe not, but there's no need to delete it. In your new question, you should link to the first one as context. Note: in your ...

You received two or more answers, in fact one positively scored answer would suffice, so you can't just delete your question. It now involves effort from other people, and that would be unfair to them. That downgrades your delete vote to the same delete vote of every other user (moderators and SE employees excluded, of course). However you lack the privilege ...

We've confirmed that this isn't a new bug related to our recent Review Queues launch. The inability to delete in this case was based on existing rules, so it's status-bydesign. We considered greying out or hiding the Delete link on posts when a post doesn't meet the rules, but this had larger implications because it would touch other places in the site, such ...

I doubt we will actually get rid of reputation points -- they're pretty deep in the StackExchage DNA, and I think they do play a role in engaging people. But how about this: Only report reputation score to one or two significant figures?

I would believe that it would be easier to edit than delete, because if you post a lot of questions that are badly received, then you can't post for a while. And no: don't repost a question you already asked. It will most likely be shut down because they are highly downvoted.
