Newsletter from members and not admin

Hi

We have a membersite (intranet or extranet) there all members that login.

Level of user is admin, author and subscribers

My question is, is it possible for a author to send a mail (SEND EMAIL TO SELECTED USERS or ROLES) but not from admin view (backend) and instead as a frontend view (webpage) for all user that are logged in?

The page I need help with: [log in to see the link]
