Sometimes you don't need everyone to approve a reservation -- just so long as somebody approves the reservation it should be marked as approved. Now that's possible to setup in QReserve and it only takes a minute!
Administration > Resources > Select Resource > Reservation Options
There's now a new option underneath your list of approvers to require all (default) or any (new!). If any is selected then the reservation will be approved as soon as anybody in the list of approvers approves the reservation.
If any of the approvers decline the request, the reservation will always be marked as declined to give approvers overriding decline ability.
