Just a small update tonight! New FeaturesResourcesA new "Unlisted to Users who Cannot Reserve" option
By popular demand, administrators can now specify a maximum reservation duration for resources under the Reservation Options tab on their Administration page for each resource.
Maximum reservation lengths are specified in hours and minutes and have no limit, so a maximum reservation length could be as short as 30 minutes or as long as 336 hours (that's two weeks!).
Regular users will be unable to create or modify reservations longer than this period of time; however, moderators and administrators are still able to make arbitrarily long reservations and modify other's reservations to be longer, so a user could request their site administrator to extend the time on their behalf.
