I'm using bitbar to solely to display the current user. BitBar is being used because "fast user switching" gives the ability to have multiple users logged in at once, plus the ability to lock the screen. Neither of these things fit in a lab environment.
I would like to make it so there is no drop down menu or "quit" function. At present, I'm going to make it so it restarts immediately after being shut down, which isn't very elegant in my view.
Why am I doing this? Students have a way of poking into corners. Even college students. I view this as a way to keep the user informed and to "polish up" the corners.
