If the RSS option is activated, the Contrexx blog module will automatically generate RSS-feed based on your blog entries and the associated comments. Thereby one directory will be created per activated system language in the location feed/, containing the following XML files:

blog_messages_XX.xml
blog_comments_XX.xml
blog_category_ID_XX.xml

"XX" is the placeholder for the short form of the language and "ID" is the placeholder of the ID of associated blog category. For example for the language german (short form: de) the complete link would be as follows:

http://www.yoursite.com/feed/blog_messages_de.xml
http://www.yoursite.com/feed/blog_comments_de.xml

For the category 1 (ID = 1) in the german language the link would be as follows:

http://www.yoursite.com/feed/blog_category_1_de.xml

For a complete reference of all short forms refer to the langauge settings in the backend under "Administration" -> "Language settings".
