I think this thread is a question for a whole mental health site, not just support forums. If you look at the top of this webpage, you see several links (home, resource directory, disorders, quizzes, ask, meds, blog, book reviews, chats, and support forums) which compose of this mental health site, called Psych Central.

What innovative ideas can you think of for an ideal mental health website??? Can't think of anything? Try Google and search "mental health" and see what other sites are doing. There's so many mental health sites reiterating the same old stuff.
