What chat group moderation tools are available?

For all chat group types – private, public, broadcast-only – group Admins and Moderators can both invite Fedians to join groups, change the roles of group members, and remove or ban members from groups. That said, only Admins can update the name of a chat group and whether or not the group is broadcast-only. For private groups with Allow join requests enabled, Admins can also review pending join requests – approving or declining each – from the group's members screen.
