While we should be happy to get a new coomunity, I think it's somewhat early to start up a new Comunity!RP. What made them great was that they came along once in a while, and other factors were:
1. we were just normal(ish) people, that got thrown into a zany situation where we all happened to meet up.
2. We tended to have nothing but our wits and a few tools to aid us.
3. They always had a clear goal in mind, thus why the few community RPs have for the most part had an actual ending.
3. It was simple wish-fullfilment- we all would have liked a chance to meet IRL, and these RPs were a sort of outlet.
If we can remember these golden rules, I beleive we have a recipe for a succesful RP.
