how to add an rss feed to my website ? or where to find it ? thnx inadvance.
Welcome to the Wix Code forums.
If the RSS feed that you want to use has a REST interface, you should be able to do this with Wix Code. See the article Accessing 3rd Party Services for an explanation. The tutorial How to Send an Email on Form Submission demonstrates a "for real" usage of implementing a REST interface.
