I have my games set up so the AD and coaches are included in the game reminders. The only major draw back of these is that they reminder doesn't include the officials or the contact information. All my coaches and directors want this feature, but I've been told it doesn't currently exist. I think this would be a fantastic feature for assigners and would significantly reduce time wasted by playing phone tag if an official is running late.
Official Information included in Reminder Email to Contacts
