To manage, add or edit, course enrollments for a user click the ‘EDIT ENROLLMENTS’ button in the users overview screen.
This will take you to the ‘Manage enrollments’ screen where you can see available courses, currently enrolled courses and completed courses.
You can then enrol users as required by clicking the checkbox on the left and selecting a coach/marker from the drop down on the right.
If required you can also un-enroll users from current courses.
Courses that the user has completed are listed in the complete section, and as such are un-editable.
