I've been a group leader for a long enough time, I don't know if I've ever had the need to find out this information.
I did some limited searching on the rules pages, but turned up no information.
If I assign someone to be manager, operator or both, what kinds of things can they do then with the facility?
Likewise, if someone is made a pilot, commander or both of a ship or vehicle, what can they do?
That SOUNDS like something you would put on the privileges rules page, but I saw nothing.
