I'm both new to oscommerce and to mods like this, so I appreciate your helping a newbie whose anxious to learn! I guess my question boils down to this: am I do do the mods before or after installation of oscommerce on my site? I had assumed after, until I got to the last step - opening catalog/install/includes/application.php. If the install directory is to be deleted (according to oscommerce instructions), why make a change there? Thanks.
