        return $form;     
    }

    /**

     */
    function register($data, $form) {
        // Create a new member and save the form into it
        $member = new Member();
        $form->saveInto($member);

        // Write to the databsae
        $member->write();

        // To do: add a status message on the form, using the standard form message system

        // Return to the original form
        Director::redirect($this->Link() . 'thanks');
    }
    
    function thanks() {
        return array(
            'Title' => $this->ThanksTitle,
            'Content' => $this->ThanksContent,
            'Form' => ' ',
