One idea is to get a list of new players who will be attending the LAN and set up a TF2 workshop. Just something to teach them how to play the game and give the newer players a little practice.
Sounds like a great idea. Set one up and advert it. Might be a good idea to offer this for all the PC games as the new guys may not be familiar with how to pwn at them.
