Ability for site administrators to see users email adresses in admin interface

[petzlux]

Detailed Description

As a site administrator, I need to ability to see any users email address to be able to contact them directly for questions.

Context

When a new user uploads questionable content, as a site administrator, I want to be able to privately message them and ask them for explanations using their email adress.

Possible Implementation

Just add the email adress as a read only field below the username in the admin interface.

We second this. Moreover, the e-mail field is also a good control for "member requests", or granting admin privileges in organizations, since it's a secure indicator that the specific person does in fact belong to the organization.

@andrelapa I am forking the issue into a new one because while the solution can be the same, it is involving different environments and issues.
