Does anyone know much about RSS feed links?

[Pangaea]

Hi, I have made a chat room for a specific forum on racedepartment called Bobs track builder
http://www.racedepartment.com/bobs-track-builder/

I have set up a script that i want in the chat that will announce the latest posts from that forum.
I have not used this script in many years and I forget what is an rss link. I saw the link down at the bottom:
http://www.racedepartment.com/external.php?do=rss&type=newcontent&sectionid=1&days=120&count=10

but this is a global announcement for the whole or race department.

I was wondering is there a link i can grab for the bobs track builder forum only

As far as i remember the rss feed links i put in to this script look something like this:
http://rss.news.yahoo.com/rss/yahoonewsroom

so i tried this
http://www.racedepartment.com/bobs-track-builder/rss
and
http://www.racedepartment.com/rss/bobs-track-builder

and a few other variations, but i totally forget how to get an rss link..
anyone any ideas?

regards
pan
