It's all up to Sakura Yume; If she decides that there are only going to be two parties, the Moron Party and the Bonehead Party, then all of these threads in General Chat are nothing more than empty posturing and will probably be closed. It's not really up to the staff, and I don't even know if Tammy reads the Feedback forum, so your best bet would be to contact her via AIM or PM or something.

I like the idea of having a minimum membership requirement for official party status, though.
