I nabbed this one off another sites source

Code:
<link rel="alternate" type="application/rss+xml" title="Forum RSS" href="http://forums.forum.com/external.php" />

It put the option to subscribe in the footer on IE and the end of the URL on FF. The php file it refers to outputs xml. So, erm, well, is that all I would need to do? I take it the browser goes and grabs the new data periodically? I originally was under the impression the rss feed somehow pushed rather than being pulled.
