Here's a (borrowing an emailer script) very simple, one-file, 15-minutes-to-set-up website referrer. Just fill in the To and From fields, and voila, it's sent. Just upload it as a .php file, make a link to it on the pages you want to be referred, and it will work. It uses HTTP_REFERER, so it MUST be linked from somewhere. You only need one file, so there's no reason to make different copies for different directories or pages. Author's Note: You don't have to credit me! This is just simple PHP. If anyone wants to to do anything else with it, go ahead and submit updates.
