I'm new to CF but I really like it here and I'm always willing to help out whenever I can. There seem to be a few issues with spammers but otherwise this is a very handy place to come and most people seem very willing to help out. I'm glad I found this site.
Suggestion(s): Perhaps custom avatars? Just be sure to set content restrictions and size limitations and just have them link off other sites in order to free up server bw.
