The PULL project we had on tracker has been deleted (only a couple of weeks ago in fact) as we no longer use it and havn't been using it for a while.
If you're interested in looking at the code change the following link shows it:
The feature itself is only available for manual enrolments and in order to be able to access the bulk enrolments you must filter the enrolled users page to show just manual enrolments.
As a guide:
- Log in as an admin/manager/teacher.
- Browse to the course.
- In the settings block browse to `Course administration > Users > Enrolled users`
- At the top of the page you should see options to filter starting with search. In the Enrolment methods drop down select "Manual enrolments" and click filter.
- When the page reloads you should see checkboxes beside each user (at the start of the row).
Bulk operations are only available for manual enrolments as other enrolment methods involve syncing users with other systems.
For these enrolment methods you should be able to make changes that will affect everyone by editing the enrolment method details.
Hope that helps.
