It's an interesting idea, but...
Having a Summer, Halloween, and Winter is already a good deal of work for the staff. They have to make the map, advertise for abit, not to mention organizing the games and such. Besides, I think the fact that there aren't many parties makes them more fun when they come around
And Alpha has a point to, that if one member party becomes official, then alot of people will start to ask.
I do enjoy the parties thou, and I can't say I'd mind to much if we had another
