The quiz should probably be limited to permanent members. Guessing the non-permanent members is just a shot in the dark, and anyway, the quiz will be out of date every time the non-permanent members are replaced.
That's not a bad suggestion, but a quiz for the permanent members has already been created by someone else. As for having to update it, I guess I'll just have to try and remember to do that every once in a while. It was something I took into consideration when I created the quiz though.
