# Subscribe users
Let's look first at how to subscribe new users as learners to the course. On the main *Users* pagetoolbar, click on the *Enroll users to course* icon *.* This will display a list of users registered on the platform not subscribed to the course:
*Illustration: Users – Action buttons*
To subscribe a single learner, just click the *Register* link  to the right of their listing.
To subscribe several learners at once, check the relevant boxes on the left hand side, then select the *Register* option in the drop-down list headed *Detail* at the bottom of the table \_(\_a confirmation window appears to ensure you want to subscribe them: once confirmed, a confirmation list appears indicating which learners have been subscribed.)
## Add teachers
You can also subscribe another user as teacher in your course. Just click the second *Enroll teacher* icon  (he's wearing a tie!) and repeat the process as for learners. Users subscribed using this link will have the status of *Teacher* on the course.
## Unsubscribe a user
You can unsubscribe users individually or as a group from a course.
To unsubscribe a single user, click the *Unregister* button  next to the corresponding user and confirm your choice.
To unsubscribe a group of users, check the relevant boxes on the left side of the table and select *Unregister* in the drop-down list headed *Detail* at the bottom of the table, then click *U**nregister**.*
**Note** : As a teacher you cannot remove the main teacher of a course (by default described in the listing as Trainer) from this screen. Only the platform administrator can do that.
## Add/update a user's description
* Click the *Edit* icon  to the right of the relevant user's entry to view the user's basic details;
* Complete/update the *Description* field to inform other users of the role played by this user;
* Save changes.
The *Assistant* box (previously titled *Tutor*) allows the teacher to assign a special *Course assistant* role with its corresponding permissions. These permissions allow the assistant to view test and assignments results from other learners in the course, to help him assist the teacher in this role.
## Search for a subscribed learner
If the teacher needs to find a specific learner in the list of users subscribed to the course, the search feature will allow him to find one or several users from all or part of his first name or last name.
Just fill in the search field with the relevant characters and click the *Search* button. A list of matching users will be displayed.
## Export the list of subscribed users
You might want, (independently of the backup copies taken by your careful administrator!) to keep a separate copy of your users list. To do so, from the main *Users* page, click one of the export icons in the toolbar (*CSV export*  *Excel export* *\_* *\_or .pdf export* ) to download the list of users in the corresponding format.
> **Note**: not all users details are exported through this feature (their passwords, for example, are confidential information not available to other users, not even to the teacher).
## Display learners reporting
The teacher can directly access details from the main *Users* page about each learner's participation in the course by clicking on the *Reporting* icon  next to the user's listing. This will link to the L\_earners details in course\_ page, described more fully in chapter 15 above.
