Neat, I like how access is so easily controlled by the user group. I did notice that I had to slightly modify how I setup the path to my forums. My forum is in a folder called forums just below my docroot. If my example file is in the docroot (ie, above the forums folder) I had to set the full path as:
PHP Code:
define('FWD','forums/');
That's running Suse with Apache2.
