Is it possible to display RSS from only certain categories?

this is just an example.. But you will need to find out which category you want to display.

Thanks Hjabb! Is it possible to display feeds from two categories in the same fashion?

Yes. Just use ?cat=1,2&feed=rss2. You can include as many cats as you want, comma separated.

Fantastic!!!

This is just what I came here to find out.
didn’t even have to ask.

Thanks!
