Comment:
I like Phil's idea (Turn off the computer, or make it available for others.). We still need to find a good title for the entry itself, though.

Currently it is "Log out %user...", which doesn't match what the dialog actually does. I suggested "Exit...", but you guys may have a better suggestion.
