Daily fetches an RSS feed and posts a list of links as a digest post to your blog. (Note that this is in pre-ALPHA development).
Digest Post fetches an RSS feed on a regular basis (usually daily) and posts a list of links to the newest articles as a digest post to your blog.
In order to run daily, it leverages the WordPress "cron" facility which was introduced in WordPress 2.1. Therefore, this plugin won't work with any versions older than that.
Please note that this plugin is in a very early stage of development. It currently has no Admin pages to configure it with, instead you need to go into the plugin's PHP code to set it up. However it is planned to have it completely configurable through a WordPress Admin page.
