This question has been asked here but no general solution is given.
I have asked a question which has been upvoted a few times, I added a bounty, but now the bounty is finished and I still have no comment or answer. I purposely don't give the link to the question I'm referring to - at least for now.
Some people tend to think mathoverflow should be considered as a completely independent site (see here, for example). Is this official, and how should I ask my question to matheoverflow then?
Let me add that I don't know if my question is research-level (in maths), but some researchers tried and have not found any satisfying answer.
