As already said, get on mIRC, try for some clans and see what happens.
I can't really suggest any clans for you since i haven't seen how you play, but going by what you said i assume you haven't matched alot/ if at all. So maybe try [3iob-t] to get a feel for the matching scene, then try for some better clans.
Also get ventrilo 3.0 , a headset/microphone.
Btw, are you european? or american?
