Forum RSS feeds?

Can anybody help me set up an rss feed for the forums?


I'd like to pull the video game deals using RSS, which according to the FAQ (copied and pasted below) should look something like this:


http://www.cheapassgamer.com/forums/external.php?type=rss2&forumids=11


But that gives me nothing. So it's either disabled or I'm missing something. Help!


Thanks
Ryan

The administrator may have enabled RSS syndication, this allows you to view newly created threads in guest viewable forums without visiting the board.
The feeds are currently provided in two formats, RSS and RSS v2. The differences are as follows:

• RSS 0.91 - This feed is based on a standard written by netscape and provides a link and the title of the thread.
  http://www.cheapassgamer.com/forums/external.php?type=rss
• RSS 2.0 - This feed contains title, author, date and the contents of the first post of the thread.
  http://www.cheapassgamer.com/forums/external.php?type=rss2

To add this to MyYahoo click here.
The forums to which this applies can also be limited to specific guest viewable forums by adding another parameter to the URL containing the forumids as follows:
http://www.cheapassgamer.com/forums/external.php?type=rss2&forumids=123

If you would like the content to be generated for multiple forums you can separate the forumids by commas.

I'd like the same thing except for threads. I've got a couple threads I'd LOVE to follow via RSS.
Or some system which I could then turn into an RSS.
