Hey guys - I posted something similar to this in the Battlefield section (not GFC). My clan recently got sponsored by a group called PGL (vgtoc.com). They're doing some cool things and I thought I'd just let you guys know about it in case you're interested! You can do 2v2, 3v3, whatever you're interested in or be ranked as individuals. They also provide the match server which is kinda unique. They only have CS:S up right now but apparantly they're adding 1.6 soon. I thought I'd just let you guys know about it in case you wanted to sign up individually or as a team. Anyways, check it out if you want 
They have other games there too.
