Original contribution is located here: http://addons.oscommerce.com/info/6646 I don't suggest to use it on production sites because I see that 1.03 version is not final: I had an autoinstaller for 1.02 and a new account was created when the password field was entered on the checkout.php page. I have upgraded to 1.03 and see that the password filed is present but a new account is not created if you fill it. I have changed only one line in the: includes/classes/onepage_checkout.php to fix the checking if the Gift Voucher Contribution is installed
