Thank you for all that. I now realize the "vulnerability" of our Moodle is that most of our courses are enrollable (this allows students who got forgotten to enrol themselves). I was thinking, my brainy student can enrol himself in other courses if I make him a teacher - but he can do that already!
Thanks Mary; as usual the simple solution is the best one!
