Currently Orion Maps are locked in by the user that creates them. How about a "Public" and "Private" setting for Maps so that a group of admins can update maps as needed without having to create a new map.
@pkbrennan is this more about "viewing" maps or "editing" them? This sounds like you are wanting multiple users to be able to openly edit another users map if that map ownership was set to "public" as an example. Is that accurate?
Yes that's it exactly. My thought was that if it's a "public" map and the user has editing rights then they can modify the map.
