Okay so here's some stuff
The Role of GM outside of an Event
Keep the peace, solve any issues between players fairly(kind of act like a moderator), and facilitate things going smoothly. Oh, and participate, this is here for everyone to have fun, just don't abuse being a designated GM.
The Role of GM inside of an Event
Run the event with the designated mechanics, if any. Facilitate an enjoyable RP experience. Oh, and you can kill a PC, don't be afraid to do that because sometimes people do something stupid enough to deserve it.
What's an Event
A more organized and structured RP with a specific goal in mind. Players sign up and mention a specific character of theirs that is going to be in the RP and then the GM(s) running the RP will initiate and run it. Note, if you do something stupid as a player your character may get killed.
I approve. I will be setting up the boards for it on the morrow, sorry Lorknis, but you kinda list the poll here.
