From your Dashboard, navigate to the “My Groups” panel, locate the name of your Group, and click on the Members Link. To change a learner's role, for example: to promote them to a group admin, or delete them from your group if they are no longer with the organization, find the user, keep your cursor in the user's row, and find the “Action Column” on the right. To change their role, click “Change Role”, and in the pop-up window, make your selection, and click “save”. To remove a user from your group, select “Remove” from the Action Column, and a pop-up appears to confirm your intention. Do so by clicking “OK”.
