If you aren't terribly interested in joining a clan that requires scheduled practice, matches, etc., then come take a look at http://clanunisol.com. =UniSol= is a clan that is more driven to the enjoyment of the game and meeting new friends, after all we do realize that sometimes 'real life' has to come first! :D While we are a competitive clan, we don't require that you be a member of the competition team or require attendance at formal practices. Instead we strive to create a friendly community of gamers.
We also are not limited to BF, although many of our member play it. Some other games we frequent are Raven Shield, Ghost Recon, UT, UT2k3, America's Army, Planetside, and Day of Defeat.
If any of this peaks your interest, check out our website, email or PM me, and I'll answer any of your questions. :)
