Customer has over 35 mailing lists and way over 1,000  users.  They need a way for their admins to view a user account in the admin portal, and see all the mailing lists that user is a member of, without having to open each mailing list individually to view its membership for the presence of that user.  Very time-consuming.

Feature Request:  Add a way for admins to view a user's mailing list memberships in one window.

Please UP-VOTE if you agree.
