I don't know if this has been posted elsewhere, but I discovered that WP can create RSS and ATOM feeds based on categories. To do so, simply add
?cat=cat# to the end of the feed URI. Nice!
This is a feature I have been using with my NucleusCMS-based weblog to feed specific categories to static web pages. Great to see I'll be able to do the same in WP.
BTW: WP's method of doign this is much easier than how I had to set it up in NucleusCMS. In NucleusCMS, you need to modify templates and skins, plus create a separate .php file on the server for each category feed.
