If you know a site supports RSS, you can manually enter the RSS URL above and it will be added to your page. Not sure of the RSS URL? Follow these 5 steps:
1)  Go to the site or do a quick web search if you don't know the URL. 
2)  Look for a little orange button like this: . This indicates the site syndicates its content. Usually, the button points directly to the site's RSS file. (The page looks like raw code, but don't let it scare you!) 
3)  To find the RSS URL, right-click on the orange XML button to "Copy Shortcut." Or click on the "XML" button and use "Ctrl-C" on your keyboard to copy the URL found in the address bar of your browser. 
4)  Return to this page, use "Ctrl-V" to paste the URL into the field above, and click "Add". 
5)  A valid RSS URL will take you to a preview page where you can see how the module will look on your page. If you like what you see, confirm by clicking "Add."
Congratulations! You've just added a new feed to your page.
