I am in the process of setting up my course. Much nicer than the Black-Board I am used to. One thing that would be a bonus is to have more than 1 level of teacher. It would be nice to give others some of the administration priviledges but not all. So that a 'tutor' could for instance set a quiz but not change other parts of the course. Can this be done at the moment.
I don't think there is anything else in there at the moment, certainly not any way to restrict what things a teacher can do with a course.
