I would like to have an option to approve a booking before it is considered accepted. Right now it is automatically accepted. What I would like an option to do, is set it up so that once someone book a slot, it will be marked as unavailable in the front end, bt in the email to the custommer it is made clear that the booking is not yet accepted, but pending approval.

Once I have look at it, i can approve it and it will automatically let the customer know its all good and turn it into an accepted booking, Or i might need more information and contactem for more information first.
