I am primarily using MSE to prepare for my comprehensive exams, and I think that it is a wonderful place to discuss mathematics. I notice that, after the summer season, ie., when school's in session, it seems harder to get feedback, comments, hints, on questions.
Are the people who are in the position to help...just wary of helping, because they may think that the source of the question is from assigned homework problems?
If so, would my stating that the source is from old exam questions help generate more discussion for my questions?
Thanks,
