On some of the other forums that I am apart of they have clans and guilds. Each clan member has onething in common. Now for this site we could do camps like The Gracie Camp or The Lions' Den Camp. You can only be a member of one camp/clan/guild or whatever you want to call it. Each group has a leader and it's followers and some sites have monthly contest between the groups based on the contest criteria. This is just a suggestion.
