We had to put our email in to get receipts and so on from Eventbrite, so my email is in the system. They had us put all the information you would put in when preregistering online on tablets at the counter, so it's not that exactly...

Here's what was in the receipt:
All ticket sales are final. There are no refunds, ticket cancellations or transfers.
Only the ticket purchaser can edit information after the tickets are purchased. An Eventbrite account is required to make any changes, and can only be done before August 31 11:30 p.m. (PDT) (Final time is TBD). To make changes, click the order # on the confirmation screen or email receipt after making your purchase, sign up for an account, and proceed with your edits.

Each Fan Festival ticket bearer will receive a select number of goodies at the event, including an in-game item (details to be announced later). Please note however that these items will not be shipped and can only be received at the event itself.
Hopefully this gets sorted out.
