When someone posts a question, which asks for verification of their proof of something, the mathematical content of that question will often be a duplicate of another question. Now, in order to help the asker, the question should not be closed as a duplicate, since it is highly unlikely that the...

What I am going to bring up is not a new problem. It was hashed again and again and again. It was brought up as far as 2013, and repeatedly almost every year. See 1, 2, 3, 4, 5, 6, 7, and 8. Some of these questions discuss whether or not it makes sense, or what to do when the supposed proof tries...

Solution verification and proof critique. This is something I go back and forth with. On the one hand, we should encourage people to post their own proofs, and it is a good thing when you can post a proof, and knowledgeable people will read it and comment. But (1) this has very little archival ...

I envision a site where people could post their proofs -- either as answers to textbook exercises or revisions of current textbook proofs -- and get feedback on which parts might need improving, and perhaps how this might be done. This sort of site could be useful to a number of people. Namely, ...
