I emailed the QuakeCon staff about the rules hosting tournaments, here is the official statement. Some of you may find it useful.

BYOC tournaments really bring the Quakecon community together like few other things can. They're a great idea for you and friends, neighbors, or the whole BYOC to take part in!

However, there are a few rules to follow when starting your own tourneys in the BYOC that we ask that you please follow:

• You may not accept sponsorship from any third-party companies for your tournament or use your tournament as advertisement for any company or group.

  • You may not publicize your Tournament as being officially sanctioned by QuakeCon.
  • Any prizes for your tournament must be offered out of pocket or from the generosity of donors.
  • You may not charge any kind of entrance fee for your tournament, even if it is to be used as prize money. That's called gambling and is illegal.
  • The QuakeCon staff reserves the right to impose additional restrictions at a later date or to cancel any tournament at any time for any reason.
  • If you need some advertisement for your tourney, stop by the Info Desk, and we can post it on a bulletin board or add it to our digital signage.

I also encourage you to take a look at the unofficial forums and /r/quakecon subreddit to see and possibly coordinate with any other SC2 tournaments that may be springing up there.
