We have multiple resources available for users to book so that double-booking never occurs. While this works just fine, users are not informing us that they need the equipment setup until literally minutes before the meeting's scheduled start.
 
Is there a way to have specific resources inform an admin that they have been booked? Essentially, if a user books a projector, I want to be notified so that I can put it in my calendar and be able to have it setup in time. I've poked around the Rules wizard, but have not found anything that works. Because users technically cannot send emails, none of the rules will work; requests to reserve the resources are not emails, rather they are calendar events.
 
This isn't a pressing matter, but it would be nice to smooth this out.
