On page 541 of the text, it states that the file forum_styles.php is inclueded with the download. I recently downloaded the code from the site, and the only style sheets in the download are for the html pages that display the code for each chapter. Any chance that the missing css file can be available for download

There is no such thing as a stupid question, unless you ask it more than once :)

This should probably be a sticky:
