This script is pretty unique in which it allows you and/or other webmasters to put together a weekly (or whenever you want) newsletter. You simply add the webmasters to your database via the admin panel and put the subscription form (examples included) on your websites. Each webmaster can login to their own control panel and submit their new articles for the next newsletter and view past articles they've submitted. You can send an email out to all the subscribers, just the webmasters, or both at once. Each webmasters submitted article is automatically included in the form used to send out the newsletter, you can do any editing to the newsletter in the form (if needed) and then simply click the "Send mail" button to send it away. This is a great way to make sure you have plenty of content in your newsletter (multiple webmasters) and a large member base as well when you are all working together to put it out.
