Hello, I am trying to implement a simple email newsletter system for about 20 subscribers.  I have been searching for a while for a simple PHP script or something that will work.  Would there be a simple way to be able to create a form email (html or text-only) and then be able to easily (i.e. without having to have a website, or webhosting) send the newsletter to multiple subscribers?  I have been looking to see if there is some service that provides email forwarding to multiple addresses at once (i.e. we could generate the newsletter, then email it to one email address, and it will get forwarded to all the subscribers.  I am trying to make it easy for someone who has only a very basic knowledge of computers and email to send a newsletter to those people in the list.  Any ideas? Thanks, Nikbone
