Team games

[Tinners]

Does anyone out there know how the frick to go about organising team-based manshoot games? I have about 4-5 willing players wanting to play some semi-regular team based FPS. Could be Counterstrike, Battlefield, TF2, whatever really.

I've come across a few websites like Clanbase, Enemydown and others, but they don't appear on first glance to be very active. I would guess that loads of people are playing BF3 right now, should be some place where you can find teams to play against?

EDIT: forgot to mention that we are, to use the appropriate terminology, noobs.
