Is there a way to turn off overbooking from the backend? You can add more registrants from the backend than are allowed at the event. It does not stop you from booking an event if it is full. It also does not show the number of available spots left. One of the two items would be great.
Unfortunately, we don't have support for this feature yet. The overbooking checking only implemented in the frontend. From backend, we have no check for it (haven't had any one complain about it before - I think from backend, you should be able to do what you want).
