Hey - Do you know how many people there are here? I've been on this site for 2 years, and I can't keep up either. I feel lucky if there are 3 or 4 people who would notice if I was gone... and it's not even usually that many!

It's not high school and I don't think people should see 'cliques'. There are groups of people who have gotten to know each other well by spending time in Chat, but I have never once seen any incident where anyone was intentionally excluded.
