Location: Administration > Appearance > Course managers
The course managers setting allows an administrator to control who is listed in the course description.
By default, users with the role of teacher in a course are listed in the course description for that course. If a course has several teachers, the course description can become rather long. In this case, you can create a role e.g. head of subject with no capabilities set and assign it to selected users in addition to their teacher role. If you then select only the head of subject role in the course managers setting, the course description will be shorter.
