Blog comments RSS feed
The Blog comments RSS feed web part can be used to create an RSS feed of comments in some Kentico CMS blog. It uses a built-in blog comments data source as a source of the blog comments. It displays a link leading to the feed, which is located at the URL of the page where the web part is placed, with a querystring parameter appended.
The web part belongs to the Syndication module. Full documentation of the module can be found in Kentico CMS Developer's Guide -> Modules -> Syndication.
