Info Desk
The info desk is your one-stop-shop for anything related to what's going on at QuakeCon 2007. The people staffing the desk can tell you where events are going on, how to get there, and also get your own events announced.
BYOC Tourneys, giveaways, and other fun activities can benefit from more exposure, and the infodesk is the place to get those things announced over the PA or posted to the intranet.
If it involves getting the word out about something, then the InfoDesk is exactly what you're looking for.
