Well first of all, if you are looking for a clan, you must be competitive, which means no double bladed saber cheat mode...and you don't just ask to join a clan, especially on here. As for a good place to look, go to www.teamwarfare.net
, and go to the recruiting section of their forums, as they have numerous clans recruiting. If you would like to try out SofD (the clan I am currently part of), then go to www.clansofd.net
and fill out an application form.. you will be notified of practices, and will have to show off your prowess on these practices (CTF) to be considered a full member.
