User roles in a group include Admin, Moderator, and Member.
Admin: The person who creates the group is by default the admin of the group. Admins can add or remove members anytime, enable or disable built-in apps, moderate posts, and comments made in the group, and lock archive or delete the group.
Moderator: The moderator checks posts and comments before they can appear on the Group wall. The moderator can approve, or edit, or delete posts and comments made in the group before they could be visible to everybody else. By default, all group admins are moderators, but any group member can also be added as a moderator.
Members: Members are added to the group by the admin. They can post and comment in the group and access all the enabled built-in apps.

- Click the Member count in the to-right side of the Group page.
- In the pop-up window, the Group members get listed.
