Community and *.tiki.org site organization

can I have rss feeds based on sections of my blog. i.e. I have a section called Africa, Asia, etc. with news specific to those continents. Is there a way to have separate feeds for those that are shown as rss modules on the first page?

I tried post the articles rss by creating a new rss mod with that link and making it visible on the front page and it crashed the whole tiki cms, had to unistall.
