It may be that you have a pre-defined, existing Curatr group of people that you wish to enrol in a course. Ideally you should link that Group to the course when you create the course - but we all forget, or perhaps the Group didn't exist when the course was created.
Here's the process to enrol a Group onto a course:
Admin Area > Courses > Your Course > Enrolments
- Click on Enrol Groups.
- Select the correct Group from the drop-down and View this Group.
- Click on Select All (or select named individuals).
- Click on Enrol Selected Users.
