Beyond the options that are available in the previous two tables, with public usergroups, you can:
Add Usergroup Leader – this allows you to specify the username of a user who will become a moderator of the group. He or she will be able to approve and deny requests to join the group.
View Join Requests – as an administrator, you also have the ability to moderate each public usergroup. This page allows you to perform these moderation duties; see below for detailed information on this page.
