We would like the ability to not allow people to register online for a timeslot that has passed. Our ice arena offers a discount for people to pre-register their ice time at least 12 hours in advance. If they register when they arrive, they are charged full price. Some people are taking advantage of the online registration by registering online at the discount as they arrive. We spoke with Angie from Sportsman about this and have a work-around, but it involves us having to manually open and close registration online each week.
