[wp-hackers] Excluding a category posts from feed and a little question

[Christopher Bratlien]

When I visit feed://www.websoftdownload.com/?feed=rss2&cat=21 the feed
contains a different set of posts than if I visit feed://
www.websoftdownload.com/?feed=rss2&cat=20 or feed://
www.websoftdownload.com/?feed=rss2

Did you already find a solution to your problem?

Your code seems valid to me. I've used a similar method to exclude posts
from RSS feeds before.
