I'm a fairly recent arrival to math.se. I've asked a good amount of questions (and learned a lot from the answers). But I haven't had the chance to answer many questions.
I've been perusing some of the user profiles for the top users, and I see a variety of university faculty, very strong undergraduates, and hobbyists who know their field very well.
I try to answer others' questions when I can, but I know up to undergraduate-level mathematics, and since more people know how to do those techniques, those questions are answered very quickly.
So: are there other ways that I (and people like me) can help contribute to the site in addition to asking interesting questions?
