I am new to magento. I have override the Contact form, but in home page not displaying the Contacts link.

my code is:

etc\module\Easylife_Contacts.xml

 <Easylife_Contacts>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Contacts/>
            </depends>
        </Easylife_Contacts>

magento\app\code\local\Easylife\Contacts\controllers\IndexController.php

<?php
include_once('Mage/Contacts/controllers/IndexController.php');

class Easylife_Contacts_IndexController extends Mage_Contacts_IndexController
{

    const XML_PATH_EMAIL_RECIPIENT  = 'contacts/email/recipient_email';
    const XML_PATH_EMAIL_SENDER     = 'contacts/email/sender_email_identity';
    const XML_PATH_EMAIL_TEMPLATE   = 'contacts/email/email_template';
    const XML_PATH_ENABLED          = 'contacts/contacts/enabled';

    public function preDispatch()
    {
        parent::preDispatch();

        if( !Mage::getStoreConfigFlag(self::XML_PATH_ENABLED) ) {
            $this->norouteAction();
        }
    }

    public function indexAction()
    {
        $this->loadLayout();
        $this->getLayout()->getBlock('contactForm')
            ->setFormAction( Mage::getUrl('*/*/post') );

        $this->_initLayoutMessages('customer/session');
        $this->_initLayoutMessages('catalog/session');
        $this->renderLayout();
    }

    public function postAction()
    {
        ....
    }

}

magento\app\code\local\Easylife\Contacts\etc\config.xml

<div id="messages_product_view"><?php echo $this->getMessagesBlock()->getGroupedHtml() ?></div>
<div class="page-title">
    <h1><?php echo Mage::helper('contacts')->__('Contact Us') ?></h1>
</div>
<form action="<?php echo $this->getFormAction(); ?>" id="contactForm" method="post">
  ....
</form>
<script type="text/javascript">
//<![CDATA[
    var contactForm = new VarienForm('contactForm', true);
//]]>
</script>

Can anyone tell me where I went wrong?
