CMS Made Simple Forums

I've been trying to find a quick efficient way to generate RSS feeds of, say, the latest 3-5 RSS feeds. I know I could just make a simple one. I can see a way to place RSS feeds on my site - but I want to provide RSS feeds (not using a third party solution with a different URL)

Maybe somebody knows of a solution for this?

Edit: I should also add that CGFeedMaker shows as incompatible with my install of 1.11.7
