An Event Request is the same thing as a Facility Use Request submitted by either a district staff  or a community user for an event using a district space (or spaces). These Requests are managed via the Admin > Manage Requests screen.

A District Group Request is from a staff member who wishes to allow specified district staff to submit events into ML Schedules™ Software on their behalf.

These requests are managed in the Admin > Manage District Groups screen.

Email notifications are received by district Admins for both types of requests.
