Sorry, I haven't used Feeder. That's the URL of the feed and it should be inserted wherever you're going to subscribe to it or use it for other things with the data. Also, if it helps, some browsers and e-mail clients (like Firefox, IE, Outlook, and Thunderbird) have support for RSS feeds. If you open the link in Firefox or IE you can see a better visual of what it contains than in Chrome or Opera for example.
