I doublechecked, keith is right, Default Settings don't have the Controlled By as an option. Ed, how about the suggestion to promote everyone to use Co-GM mode? keithcurtis said: It's possible for the API. I don't think that "Controlled by" is something you can set as a default, though. There might be some workarounds, depending on your use case, though. The simplest thing to allow universal control is to promote all players to GM status. Without knowing your goal though, this might be overkill.
