A read-write display string used to rename a user group; setting it changes the group's name both in this table and in every matching entry in the cmMemberTable. Because this rename cascades to member entries automatically, an admin uses it instead of manually updating every member's group reference one by one. An admin standardizing naming conventions would set cmGroupNewGrpName to rename an old, inconsistently-named group, trusting the system to update all its members in cmMemberTable automatically.
