The Registration Secure Question is ideal for reducing the number of Spam registrations on a PHP-Fusion site.
When a user go's to register on a site they will be redirected to the Registration Secure Question page (secure_question.php) Users must answer the security question correctly before proceeding with registration. When the Secure Question has been answered correctly a cookie is then set for 10 mins and the Secure Question page will be redirected to the registration page (register.php) where the user can proceed with registration.
When the cookie expires the user must answer the security question again.
