It would be great if we could give individuals access to edit specific web pages but not add/delete or edit other pages. One use for this would be to give Patrol Leaders the ability to edit a patrol specific page with whatever they want to have out there.
Similarly, the ability to edit calendar events in a similar fashion - lock it down to perhaps a specific event type for what they could add/edit? That way we could setup patrol specific event types and they could put their patrol outings on the calendar.
