I like the system, it works well.
However, my problem with it is that the match admin cannot add people to the squads himself. So, for example, if 8 people sign up online for a certain time, and then 5 people call in or mail their request for that time, you will have 13 people shooting. I find that you have to constantly check back and forth between the paper/electronic schedules.
If there was a way for the admin to add mail/phone registrations to the squadding lists himself, it would solve that problem IMO.
