Part of the reason we opened the Eastern Front of this convention was to relieve some of the pressure on the PAX Prime, but the show has its own momentum, and it's barrelling toward Boston with full force. What this means is that if you want to attend PAX East at the end of March, you should preregister now. We're already looking into an expanded venue for next year - we saw at a couple solid candidates when we were out there originally, so that's already being managed. In the meantime, though, yes. You want to preregister.
That influx also means that more volunteers for the noble Enforcer Corps are more than welcome. An application for doing just that can be found here.
