This is a rss 2.0 writer class based on rss2.feed.class.php from the "Feed Writer Classes" add-on for Geeklog 1.3.9.
It basically gives you an improved Rss 2.0 writer that works with Geeklog 1.3.11. Other versions untested.
You need Geeklog 1.3.9 or better. It works with 1.3.11 but the RSS writer interface might change in future version.
Download the rss20.feed.class.php.r?.txt and rename it to rss20.feed.class.php
Place the .php-file in your ../system/classes/ directory and you're done. You'll find a new RSS file format in your Content Syndication menu. It will be called Rss20.
Look at my feed at http://weblog.christoph-probst.com/backend/stories.rss2. Sorry, it's all German but you'll get the point ;)
Look at my contact page.
something.rss2 make sure that your webserver has a
mime type for that filename. For example add AddType application/rss+xml .rss .rss2
to your global httpd.conf or to an .htaccess file placed in the public_html/backend directory. Read
