This module provides a searchable view of Group Membership and allows authorised users to add/remove membership and admin status. It offers search and display of users' real names, user names and email addresses, with flexible access control.
Version 2 Enhancements over Version 1
Much more flexible configuration and access control.
The module can be used to provide a searchable member list (no admin access) for users/members.
Can promote/demote administrators, including make user member+admin in a single pass.
Separate help pages can be configured for group admins, members and visitors.
Flexible access control, e.g. allow non-members to view/search for admins but not view member list, or allow members to view/search member-list but not non-members list. Access to sensitive data (real names and email addresses) can be limited in a similar way (see screenshot.)
Can work with users' real-name data held in standard Profile.
Clean, simple, light. Almost CSS-only design, styling the default output of Drupal core. Only a couple of small changes to re-order that output in a few basic templates.
