If Email display are not turned on then Admins cannot see the emails of their members in the backend, this makes it difficult to provide customer service because often members emails and names do not match (aka. Meredith Smith, kickass1978@gmail.com). My members do not need to see other members' email addresses but my admin does. It would be nice to be able to see the member's emails in the "analytics" or "all user" section so we can provide excellent customer service. Thanks!
