All good dude, I think we're organising a match-up on Thursday night (right guys?) so then would be a good time. Basically a squad can just spawn on each other, and you can see where they all are in green instead of blue arrows (and it shows the name on top of the person, as well as the class they are). If you've got a good Assault class with you, you can go on a rampage: Most maps it's best for 2 engineers, 1 support and 1 assault in a squad. You get extra points for having squadmates spawn on you, for helping them out with suppressive fire, etc etc... Basically, the more stuff you do together, the quicker you level.
I'm only on lv7 or 8 now, and that was in one night of LANning with mates... If you can, grab a mic before we play and hop on the teamspeak server, makes getting squads working together well
