Per the original announcement:
You can play this tournament as long as you are affiliated with a school in the ACF sense of the term. If you are unsure of your eligibility status, you should contact us or your TD. Also, there will be no open teams allowed at this tournament, no matter what the reason. Chimera or scab teams are only allowed for the purposes of filling out a field. People who need to play “unaffiliated” for whatever reason should contact us to resolve any issues. Exceptions might be made if there is some scenario I haven't envisioned here, but that's not likely. Play with your own schools people!
Essentially, eligibility at this event works like ACF Fall or EFT would, but just let the TD know if you have any questions.
Base fee: $120
Buzzer discount: -$5 per functional buzzer system
Staffer discount: -$10 per functional moderator
Travel discount: -$10 per 200 miles one-way (as determined by Google Maps)
Sandy Huang will be serving as TD for this event. To register, email sunhuang AT stanford DOT edu. Feel free to post in this thread to express interest, but you won't actually be registered until you email Sandy.
