I was lucky enough to get through the gauntlet and after the second time, get fully registered for Botcon 2011! I purchased a Primus Package as well as a loose bagged set of the Stunticons. I also will be attending the customizing class for the first time. That should be fun!
The site is being completely overloaded right now so my suggestion is to be patient and fill out your information as quickly as possible! The first time I went through, I was unable to complete the registration before the countdown ended.
