I'm having trouble with the "clickish" comment, probably because I've been accused of being a part of one and that is SO NOT TRUE!

IMO, you just have to get in there and start talking, at least to just one person and first. You'd be surprised how quickly others start responding to you... Or at least, that's the way it USED to be.

Honestly, though, in the past, if you didn't speak up much, people would tend to forget you're there.
