Hi Doug,
If you ran Notifications from Site administration the permissions would be granted by the access.php file. I've not had a case where this failed. If you need to manually assign permissions, from the Moodle front page:
- Site administration
- Users
- Permissions
- Define Roles
- Edit the editingteacher and student role searching for laegrader and laeuser.
You might want to disable the regular grader and user reports for these roles though some leave both. You cannot remove the Grader report from your site as many of the functions cascade down. Let me know how it goes.
