I am looking to find a forum in the Internet intended for math enthusiasts to discuss math ideas outside the question-answer format but at high level. Can anyone advise such sites?

This is a place where we could collect list of chat rooms associated with this site. There are several rooms which have potential to be useful if more users were aware of them or more users visited them. Collecting a list of such rooms here could increase their visibility. This was previously dis...

Would there be an interest in having more specialized chat rooms, like the one for homotopy theory that currently exists? So far, the homotopy theory one seems to be fairly successful, and it seems that other topics might also enjoy a chat room like it. Obviously, if such a chat room is to be u...

I want to ask about various mathematical fora and discussion boards available online. I think it might be useful to have such a list here at Math.SE. If I may suggest, it could be useful to keep one long list with basic information as a community wiki, and if you want add some additional informa...

I know the differences between mathoverflow and math-stack but I have been wondering: Are there legitimate mathematical questions that would not get answered at math-stack because there is no expertise around and yet would be considered trivial (not research level worthy for mathoverflow?) I ag...

The Problem: It becomes more difficult to help people on a site in which there is mass closing of questions. And I am disturbed that a small group of people is engaged in trying to delete permanently some of the questions I have answered. I interpret it as systematic deliberate erasure of my wor...
