Can now change the status of group members (delete, expire, activate, re-enable), change the functionality available to members (if group is configured to allow different members to use different functionality), and/or change member privileges for each of the functions (if group is configured to allow different members to receive different privileges). If granularity in functionality, and/or in privileges is required, but was not set to be so during initial group creation, this can be changed by modifying the default group settings first.
