The scrimmages are generally capped at 20 skaters. If, when you confirm your spot in the scrimmage, there are already 20 confirmed skaters, you will be put on the Reserve list. Should anybody ahead of you drop their spot for the scrimmage, you will be moved up the Reserve list, and eventually on to the Confirmed Skaters list. You will receive an email informing you that you've been moved off the Reserve list and on to the Confirmed Skater list. If you supplied a cell phone number when you signed up for the scrimmage, you'll also get a text message letting you know you've been moved off the Reserve list.
Should you become unavailable for a scrimmage, it is your responsibility to drop your spot, even if you're on the Reserve list.
If you get moved off the Reserve list relatively close to when the scrimmage is supposed to start, I will attempt to contact you directly to let you know, just in case you are not able to check your email.
