CampusGroups has several ways to categorize groups.
Member tags (hidden from members) allow to tag members with tags only accessible to Administrators and Officers of the group
Sub-Groups (opt out/in possible) allow to tag members as well, and tagged members can see how they are categorized
Parent/child feature allows to restrict a group access to people who have joined the group's parent group
Group Types allow divisions to manage separate sets of groups
