Hello!
I suggest to add a space for non-question posts to Math.codidact. This may be useful in the fiollowing cases:
* Pasting long pieces of text that do not fit into the question format but the questions need to refer to
* Pasting programming code, lists, tables...
* Expressing theorems, proofs that may be referred to in questions or answers, without overloading the questions and answers and allowing to refer to one piece on a topic of interest from different places
* Maybe some kinds of wikis on different topics?
