A score is a good idea.
I find it useful to hand out gold stars to the good users.
I also have a naughty step for the bad ones.

(I am only half joking - I really HAVE threatened to get a naughty step for users!)



RGB mentions the figurative use of a "sucker rod" and the related flogging. (I am assuming that he was using a short length of the rod.. The full 20 feet or so is a bit unwieldy) {I can't recall how to search the archived list so I can't provide specifics)
