As for the question of how long it takes to get a response, my experience has been from very quickly, several minutes maybe, to never. If I don't get a response in some sort of reasonable time, I just send a follow up (actually waiting for a further clarification on one right now, from early last Wednesday, that I will follow up on in a day or two) after a length of time has elasped and the question is not answered. They are very busy and some things fall through the cracks or get lost.
As for the moving of threads, the way I understand it now is, that on all the topical boards (all but this one), threads can be moved if they are off topic (the topic of that board), and on the non-topic restrictive board here, they can be moved, if considered topical for one of the topical boards, on a thread by thread basis, at a moderator's discretion. So I would just think that a lot could be moved from here, depending.
