Got in at 12:00:53, got ticket right about 2:00.
Beside the expected turn on cookies and make sure Javascript is on, I found out I also needed to turn off the Firefox "Warn me when websites try to redirect or reload the page", and I also turned off the Winblows Local Area Connection Status - Properties - "Notify me when this connection has limited or no connectivity" just to prevent any potential probs. That probably didn't matter though.
After about 40 mins, the AWS load balancing (or whatever) settled in and the wait page refreshed within a second or two then instead of up to a minute. When the purchase page happened, there was immediately a connection reset, I just clicked through the Firefox error message and the page immediately loaded. No biggies. I guessed correctly on the "Are you human" that it was a skinny 0 rather than a fat O. The confirmation email came immediately after the purchase. I would recommend that "burningman@inticketing.com" be added to your contacts list to make sure it doesn't go to spam. The confirmation email was just standard ESMTP, not DomainKeys/DKIM authentication, no hangups.
Right then, I got a package for expanding an art project for this year. All I need now is a camp and to be able to go. One step at a time

Good luck to everyone!
