It would be awesome to have a way to publicize and limit reschedule requests to a deadline, without having to delete dates from the scheduler settings.
Reschedule Request Deadline
Additionally it would be great to be able to set a restriction on sending reschedule requests within a certain time frame of the contest. I get some teams sending them as late as an hour minutes before game time.
While I agree that it would be a great way to keep students aware of policies, this could be something that you address with captains during the captain meeting. For example, our policies at Colorado Mesa state that reschedule requests must be made in writing (via email) no later than 24 hours before the scheduled game time.
Now to be honest, if I do have the staffing and facility availability, I might try to move games to help the students, but if I am unable to due to other tasks, they know the request will be denied.
Keeping the students responsible for adhering to your program policies is a headache sometimes, but it's important to teach them that there are rules and regs for everything they do!
Hope that helps!
