User Management

[#1]

I would be very helpful to provide UI administrators the ability to email all users or just a group of users.  This would help with basic user management for companies that don't use the Administrator API and cannot integrate using LDAP.  Currently you have to export a list of User email IDs and create a mailing list in Outlook or some other email program and send out important information that way.  An possible solution would be to automatically signup users to a distribution list by default.

I agree on this one - furthermore, the email tool would save the emails somewhere so that users can look them up later (use case: emails about new reports, upgrades, training, etc.).

The email groups would be based of the User Groups in the admin tool.
