Creating multiple RSS feeds from one blog

I received some help yesterday from this forum on creating two different feeds for my Web site. I want to create a press releases feed and my normal blog feed. I learned how to categorize my posts “pr” and only get them to show up on a certain page.

Now I’m trying to figure out to exclude the “pr” category from my blog.

I’ve tried looking around online but couldn’t find anything. It seems like this should be a fairly easy thing to do.

Any help would be greatly appreciated.

Thanks so much!
