I just wish they'd give the option of mailing badges out. The year Windows forced an update on them and the line ended up going down the sidewalk on the east side of the convention center, I was able to walk right in and start doing things. This year, I missed an event because of whatever problem occurred. I suggested this in the feedback survey they sent out (also told them the Dragoons need more room).
Anyhow, I'm already looking forward to next year's events!
