openSUSE Lizards: Creating Custom Feeds

This is likely interesting for more openSUSE Members blogging on lizards.opensuse.org: Yesterday Klaas asked me if he could make only his posts to the KDE category appear on Planet KDE. A short digging showed that WordPress allows to create custom feeds. So the solution was as as simple as

http://lizards.opensuse.org/?feed=rss&author=19&cat=5

You can find out the numerical IDS for categories by searching for "cat-item" in home page's HTML and for authors by looking at author links in the admin interface.
