To add a new postcard just put it in the catagory folder. You will still need a database though so people can receive the card. It uses a mime mail class, and the whole script has only 5 variables to configure. There are full instructions included. The script comes with a setup script that will guides you through the installation process.
Web based admin allows the admin person add, delete, and edit both the cards and the categories.
Very easy to install. Just one configuration file to edit. Version 1.3 includes some minor bug fixes, an SQL insert to get you started, and a feature that allows you to determine how many cards should appear per page. Also includes a french version. It then sends a message to the specified email address and saves that information to a text file.
