Dude, when you get yr team together get your ass down to a Midlands Masters event. Keep yr eyes out for info on the Tournament board.
There are usually at least 4 divisions (sometimes 5), and the ranking system is very fair. Also, it's nice to gauge yr performance against other regular teams when you first start off.
When Full-On mark 1 started off, we used to just pick up a copy of PGI and decide which ones we wanted to play and just go. It's nice to have a coupla well organised series' to pick from now though.
Also, it doesn't hurt to come along to a tourney and watch. Ask questions, you'll find paintballers are usually more than willing to share their sagely wisdom, no matter what their skill level!!
See ya soon hopefully!
