IMO it would be nice...but there already plenty of fansite forums around.

And if you look SE side, it's a feedback forum so it would be a waste of menpower effort having to moderate a forum that would add no benefit to the game. As SE, I would be very pissed if i knew i was paying a moderator/GM team to moderate a forum where people would talk about everything EXCEPT about what i wanted...my game.

It's not about talking about random stuff...it's about where you want to talk about it.
