public function indexAction()
    {
		$form = new Zend_Form();

		if ($form->isValid($_POST)) {
			// success!
			$values = $form->getValues();

		} else {
			// failure

			// deubg
			$this->view->form = $form;
			return $this->render('form');

		}

		$form->setAction('/members/index/register')
			->setMethod('post');

		$form->setAttrib('id', 'login');

		// create and confirure username element
		//$username = new Zend_Form_Element_Text('username');
		$username = $form->createElement('text', 'username');

		$username->addValidator('alnum');
		$username->addValidator('regex', false, array('/^[a-z]/i'));
		$username->setRequired(true);
		$username->setFilters(array('StringtoLower','StringTrim'));
		$username->setOrder(1);

		//create and configure password element

		$password = $form->createElement('password', 'password');
		$password->addValidator('StringLength', false, array(6))
				->setRequired(true)
				->setOrder(2);

		$form->addElement($username);
		$form->addElement($password);
		$form->addElement('submit', 'login', array('label' => 'login', 'order' => 3));

		$this->view->form = $form;

		/**
