I think it would be a good idea to at least make one during the school months, and see how it goes from there. It might open up discussion on other aspects of school and/or other things which is never a bad thing.
Why not bring up school... its going on right now and i'm pretty sure there's a lot to talk about it. Maybe we shouldn't have a school board but a topic about school.
How about all four, perhaps a gaming section or more hidden forums or a favorite section to ask like favorite color etc or something to keep us deviants out of trouble
