TOPIC: Add 2 or more recipients to Notification EMail

We\'d like to be able to have more than one email address added
to the email notification option. I tried several routines, like
some modules allow to have a second email address by adding comma
after 1st address, then adding a second address which didn\'t work.

Could be very useful when you have an organization that needs one party to handle the donation monies and other person who sends thank you letter or does other services.
