I understand but I think that I have not explained well enough how it would be an advantage.
In the context of an 11 - 18 school we have some subjects eg Maths at 6th form level that have created a number of component Moodle Courses (eg Statistics, Mechanics etc) for a single subject set of students.
At the moment we 'get around' this by creating a parent course and enrolling the students on that and then creating child courses for the component courses. This would be fine if it was only the students that are enrolled but the teachers are enrolled as well - more flexibility is needed on the enrollment of teachers.
I suppose the other approach would be a mechanism to restrict enrollment to students only.
Thanks for taking the time on this issue
