hack request : extra 'email users' feature

[sbryan]

in the admin tool you have the nice ability to email all your users at once.

what would be cool if this tool was expanded upon to increase its functionality with at least one extra feature.

to be able to use it as a more useful email engine, how hard would it be to put in a 'exlude users' box so that you could enter a list of email addresses for people that DONT want to receive any newsletters/emails that the admin plans to send out.

:bunny: :bunny:

what do you guys think? hard to implement?
