Usergroup membership can be managed through the Usergroups section of the UCP. The page lists groups for which the user is a member of, a leader of, and all other usergroups. Groups which are open for membership have a radio button allowing the user to request membership. Users may also remove themselves from groups in which they hold membership. If a user has the Can change default usergroup, they change choose which group to be their default here. The default usergroup dictates the user's username color which is shown throughout the board.
Users who are designated as a group leader are able to manage the group's membership. Users can be added, removed, pending join requests can be approved or denied, and have their default usergroup changed here.
