Qdig-WP without mod_rewrite
I recently released Qdig-WP 0.4 with instructions on how to use it when mod_rewrite is not in use. These instructions are now obsolete! A better way has been found!
The latest devel release (20050325) of Qdig has a $keep_params setting that will automatically detect the querystring and keep the parameters in it to maintain the page state. Setting $keep_params to TRUE enables this, and is much easier than the voodoo I suggested with $extra_param.
If you have it working with $extra_param, please be aware that the option may be deprecated in the next stable release of Qdig. You should strongly consider downloading the newest devel release and changing your settings.
