See if there's a club like
SPLAT at your university. If so, hit them up before hitting up the IT department, you'll probably find out they are closely affiliated with the IT department. If nothing else, that club will usually have events every few months, and get as many people together on a LAN and go to town. If you don't have a club like that at your university and are serious about gaming, look into starting one. SPLAT tournies started with 15-20 people showing up, and now they consistently have 100+ show up.
