Each forum, at the highest level, displays RSS feed icons to give you easy access to the RSS URLs for each individual Pentaho forum.

The general RSS URLs to aggregate all Pentaho forums, in various formats, are:
XML - http://forums.pentaho.org/external.php?type=xml
RSS - http://forums.pentaho.org/external.php?type=rss
RSS 1.0 - http://forums.pentaho.org/external.php?type=rss1
RSS 2.0 - http://forums.pentaho.org/external.php?type=rss2

Threads will be returned in descending order based on the date of their creation. Description information will be returned from the first post of the thread.

You can create your own custom grouped listings by specifying forumids in the path of those forums you wish to receive the feed from. For multiple forums, separate them with a comma. This will limit the feed to the specified forums only. (Below example uses xml as type, but it works with rss, rss2, and js too)
