E-Mail functionality for moderators I would like to allow moderator to send an e-mail to choosen user. The e-mail will be sent when the moderator observes a mistake made by the user. After that, moderator sends email with warning. How can I do it?
A simple solution would be, to give the moderators role the permission to use the users' individual contact forms ( in http://example.com/admin/people/permissions )

The messaging and notifications modules might have more functionality, however, they are still in alpha for drupal 7, so I would use them with great caution.
