To begin creating a group, ensure discussions are switched on within portal settings:
Portal Settings > Configuration > Groups and Discussion > Enable Discussion
From here, click into the "Discussion" tab at the top of your portal. You will then be directed to the discussions home page. To create a group click "+Create" and you will be prompted with an option to title the group and add a description and logo.
Once created, click into the group in order to edit and add users. To edit, head to "Settings" which will provide you with privacy settings. A public group can be seen by all users and a public group only by members and admins.

Learners won't be able to add or remove themselves if the Group is set as a ‘Restricted Group’.
Simply select 'Restricted Group' when creating a Group for the first time, or adjust this setting any time by navigating to 'Edit' within the Group.
