I'm guessing it has been suggested before, but I like the idea of having a forum for questions from and discussion amongst new riders.
Most new riders have a lot of questions, and it could help to have all those posts archived in one section. It would also be nice to compare stories with other new riders--what first bike you bought, what school you attended, tips for the road test, etc.
I'm sure it would be quite an active forum, and encourage new users (who are probably quite frequently new riders) to post more. Just a suggestion. The site is great at any rate.
