1) Having the t-shirts in the expo hall was a great idea - definitely agree here. We should continue to do this.
2) Having people hunt around the expo floor for t-shirts imho is a good thing, they will hopefully see booths they will want to visit in the process of hunting.
( I would have personally liked to have spent more time on the expo floor myself but found it a challenge between sessions. )
3) Could we do a better job about splitting the line between the sizes.. yes.
4) Suggest making certain there are interesting booths and/or signage promoting various SCaLe activities which people can read while standing in line waiting to pick up shirts.
Thank You
