vbulletin 3.x lets you provide rss feeds using rss, xml, or javascript.

The simplest way would be to use the javascript since you can insert that into your page. Otherwise, you could mess around with some open source rss readers and do it that way.

Oh btw, external.php (the file that generates the rss feeds) makes use of hte permissions system so you dont have to worry about people seeing threads they shouldn't.

One last thing, you can have external.php call the new threads for say 3 out of 10 forums by listing the forum id.

Its something like external.php?s=3,4,5 or something like that, check on vbulletin.com in the docs.
