Anyone is free to start up whatever kind of thread they want in their group forum, why is this an issue at all???
I tend to respond to threads mostly in Chit Chat and Greek Life. I read a lot of the threads in the D9 forums because there's a lot of great posters that don't venture out into the other forums as much and I'm sure it's due to the assinine behaviour of some in the general forums. I've always been welcomed when I've posted as well.
Ultimately...who really cares where threads get started? As long as people are talking, being respectful, having fun etc, why does it matter?
