These scripts combine with Auto FollowUp. AFU allows people to subscribe to the autoresponder by 電子メール, but this collection contains a script that will actually answer an 電子メール! It will respond to 電子メール subscribe and unsubscribe requests.
This small script will fetch X number of items from an RSS feed and display them within the content of your site. Great for putting updates on your site, or news, or even blog excerpts.
