[wp-hackers] simple question about RSS feeds

[John Black]

Forgive me if this question is like Wordpress 101.

I have a site that has categories and tags. Sometimes tags are relevant in more than one category. However, I want to create an RSS feed based on the specific combination of a category and tag.

Can I create an RSS feed that only pulls out posts that include *both* the category and the tag I'm looking to combine?

If so, how would I do it?

best,
John
