Meh, I think going to a club, TG, LGBT, whatever .. is what it is.
Getting together with a bunch of folks who have this one thing .. CDing .. in common leads to, well, talking about crossdressing. Being the new person in a group, if you wanna talk, you gotta have the temerity to talk. It might be considered rude, but it's not hard to politely move the subject around to something that interests you.
But yeah, clubs are for clubbing, forums are for foruming, small groups of friends are for talking about common interests.
