I actually was wondering about the chat room issue myself, but had kind of come to the conclusion that 'filtering' is likely the reason we didn't have one.
Still, it would be pretty cool to have something like that going if not officially part of this, then as sort of an aside.
*shrugs* I understand why we don't have one and I can see how that could go sour really fast. Even so, I'd like to think those who jump in would chat responsibly. Maybe you can bleep things out in chats too. *lol* I admit I'm guilty of needing that. Woops!
