Sounds like a significant issue as well for refs. We use to be able to register our availability in hour blocks, not just whole days. I.e available after 1pm on Saturdays, looks like comet can't handle this...

Also, I believe no reoccurring availability, so for every week of the season, confirm days of availability, not just on Saturday, though I hope I misunderstood this point...
