To start a boot vote just bring up the player list ("TAB" I think) select the players name and the reason you want to boot the kid. That should bring up the "vote to boot" for all the other players.
It's alot easier to get rid of annoying Team killers and harrassers in this version, just press F1, instead of scrolling through the whole list. Even with TK off they seem to still find ways to be annoying, like the afore mentioned crashing a ship full of teamates into a wall...
Not being paranoid doesn't mean someone isn't trying to kill you... or does it?
