It's a lively crowd and there are many players in all level ranges, guilds high and low.
In fact, last night was "Movie Trivia" night in the 50-59 chat channel. Not my favorite way to use a chat channel, I just didn't pay attention to it, but the folks are friendly and fun.
When I group I'm usually comical and light, although I make sure I don't spam my group-mates with drivle.
