I would like to know what is the relationship of the site Meta Stack Exhange and the site Meta of Mathematics Stack Exchange.
I am not member of the community Meta Stack Exchange, I don't know if this is related to the site Meta of Mathematics Stack Exchange. In particular I would like to know if I can join to this community and ask questions in a similar way that I do in this Meta Stack Exchange. I don't know what concerns are adressed on the site Meta Stack Exchange. For example I don't know if it is possible to do a cross-posted on this site, or edit and add comments on the site Meta Stack Exchange question in a similar way that I do here on this Meta Mathematics Stack Exchange.
Question. What is the relationship of Meta Stack Exchange and the Meta site of this Mathematics Stack Exchange? I would like to know if I can do questions related to some specific Stack Exchange site, for example this Mathematics Stack Exchange, in the site Meta Stack Exchange. Many thanks.
I hope that I have not misunderstood the situation of possible relationship of both sites, I want to know this information (see also the previous second paragraph) just from an informative point of view. Thus if you can to add a concise overview about my doubts it is good. I don't know what is the scope/goal of site Meta Stack Exchange.
