I need to find or create a role for users who want to observe and view all Moodle courses but they should not have any editing rights. I'd like to apply the role globally but per course category would do. I don't want their names to show anywhere (like a teacher's name shows on a class listing. And I don't want all of the courses to show up in their My Moodle page.
This is for principals and admin people who want to observe what their teachers are doing as we bring textbooks online.
Are there any current roles like this? If not, what's the best way to do this? Should I duplicate a role and edit? I don't want to mess with roles and permissions so I figured I'd ask here first.
