Is there a connection between Mathematics and MathOverflow sites? Obviously topics are similar, but I mean something like: do questions posted on one site, perhaps with certain tags, automatically end up on the other one? I have seen in the past same questions posted on both sites at the same time and I was wondering if users did it manually or not.
Also, how do I decide what topics are for overflow and what are for regular site? I know that calculating a basic limit should be on the regular site, but there are some questions that I'm not sure about. Should I post those on both sites?
I hope I'm posting this at the right place 😁 Thanks in advance
