ATOM feed which uses the RSS config file.

Advantages over rss.ssjs - Readers actually work properly (I have yet to find a single RSS 0.91 reader that follows the spec. IE7 for example WILL NOT WORK if a DTD is specified. A DTD is required by the spec. - You can *define* that content is HTML - it's designed to have the full message content... so it does!

ATOM feed which uses the RSS config file.
