I am the owner and representative of the UCC or the Ultimate Clan Challenge. The aim of the UCC is to allow clans of all skill levels and sizes to find other clans to play, socialize and co-exist with. As I am just starting up, I'm looking for Halo clans to join the UCC and get the ball rolling. Here is a link to the site. So if you're interested in joining, please message me or better yet join the UCC
