RSS (Really Simple Syndication) is a format for syndication of items frequently extracted from a Web site. The requirement is that they should be separable: such
as news, blogs, job announcements. As of version 3.1 Sitefinity supports RSS in the form of a service which provides the functionality for setting up your RSS Feeds. It
could also be implemented by external content providers.

different channels that provide information from various providers.
Customizing RSS
In order to customize external modules, some changes should be made to existing files, as well as some files should be created. For detailed information, refer to
