Wordpress Plugin: PHPList Integration
PHPList is a excellent open source newsletter manager. However, one missing piece from the application is the ability to cleanly and easily allow users to subscribe to your newsletter from your wordpress blog.
This plugin for wordpress gives you the ability to easily allow users to subscribe to your newsletter from any page on your blog. Simply install the plug-in, configure your settings, and embed the comment <!--phplist form--> on any page on your blog. It's easy and fast.
