Description
-----------------------------------

Triangle Solutions Ltd, has created a set of scripts which allows you to create a newsletter subscription page.
You will be able to create multiple newsletters on the page, thus offering users a choice of information. The
newsletters and members are fully editable, plus you can choose which newsletter to send to and it will pick
out all the joins from that newsletter only and send the HTML email to them. Users will be able to unregister
from the services themselves - so there is little maintenance with the script.

+ Create multiple newsletters through the one script.
+ Users can unregister themselves through unregister.php.
+ Admin facility allows you to edit, delete and list the members of each newsletter.
+ Send to one of your newsletters knowing that only members signed up for that will recieve it.
