A free collection of scripts to do everything from forms and password protective pages to games and mouse effects

This one is for when you want a form or special script for your site, yet don't want to pay a developer to create it. Some take a little more know-how than others, but most work easily to produce great results. On many, you still need to customize them and add your own links for the procedure – so, this one is a bit more advanced.
