In previous chapters you learned how to create users; now let's cover how you add users to groups.
Log in to your course as a teacher or administrator.
From the Settings block, select Course administration, select Users, and then select Groups.
From the Groups page, select the group you want to add users to. For this example, let's select the Safety L1 group we created previously.
Next click on the Add/remove users button located on the bottom right. You will now be on the Add/remove users: Safety L1 page. See the following screenshot:
On the right side of the page you will see a list of Potential users you can add to the group. This lists participants in the course who are not already assigned to the group.
To add a user, select the user you want to add from the list of Potential members and click the Add button. The user you just added should now appear in the left Group members column.
You can search for users in either column from the Search box below...
