I thought that we got sub-forums so that we wouldn't have to see this kind of topic anymore.
The most important thing, of course, is that we must all sternly disapprove when someone dares to have a little fun.
I know playing with our plastic toys is serious business and all that, but I don't think it really hurts anything to let a little silliness escape quarantine and slip into the main discussion area, do you? Look how often threads in the general discussion area could or maybe even should be in the theory/net-listing subforum, after all. How often do we complain about those? Not very often, right? So I don't think it's all that bad for a little light-hearted fun to leak out, too.
When even Paul Heaver makes silly starfighter "swoosh" sounds during major tournaments, it's not the end of the world for us all to grin like dorks and watch the Falcon fly around and shoot stuff for a minute or two, y'know?
