Gotcha. Can that be made a config option for down the road? One of the major complaints I hear about dynamic pages/sites is the length of the resulting URLs. Seems any chance to shorten the URL without adversely affecting the script should be taken...

Along the same lines, is $cat_id used anywhere other than selecting categories to browse? I would rather use $cat (shorter and easier to type -- some people actually do type in URLs manually and don't care for underscores) if possible, assigning the $cat value to $cat_id for internal processing in page.php. I just don't want to break something else unforseen in the process. :)

That makes sense, thanks.
