How about having a forum dedicated to marketing strategies, tips&tricks on "How to get yourself out there" and so on? During recent years the music industry has unfortunately become more and more of a business and i believe it would be good to have a board dedicated to discussing that type of stuff.
Discussions could vary from label talk (either how it's inside a label or how to get onto a label), how to effectively promote your material, how to stay consistent with your music and your profile. Basically that stage where "i feel that my music is good enough for everyone to hear, now what do i do?" or even give the opportunity for big label owners to have their say on what they take into consideration before signing someone, etc.
