The registration setup was miserable, and the scanners didn't work. Who thought up that traffic flow pattern? We're going to come in, cross through ourselves to get in line, then cross through again to get out the same door, when the building clearly has front and side access? Set up a bunch of stations, have a bank style line, and when a station frees up, someone goes to it. Or just do what Fry's does and have someone directing you to the next available station. People come in the front, enter the line, hit a station, and depart out the side door. This has the added side-effect of keeping people from coming IN through that door, which is what happened around 11:40 when people all crowded in because we all thought something was starting. I definitely did not go to join an impromptu mosh pit, but that's what we had for a while there.
