Walled Garden message in Cool Theme 2.1

Hi

I have zero .php coding knowedge - so hoping somebody can throw me a bone and tell me what / where I need to edit. 

The Cool Theme 2.1 for Elgg 1.8 shows the following message on the login page: 

A message you can edit in cool_theme/views/default/core/walled_garden/login.php :-).

What / where do I need to edt this file in order change this message?

This is my file: 

<?php
/**
* Walled garden login
*/

$title = elgg_get_site_entity()->name;

/**
$welcome = elgg_echo('walled_garden:welcome');
*/
$welcome .= $title;

$menu = elgg_view_menu('walled_garden', array(
'sort_by' => 'priority',
'class' => 'elgg-menu-general elgg-menu-hz',
));

$login_box = elgg_view('core/account/login_box', array('module' => 'walledgarden-login'));

$content = <<<HTML
<div class="elgg-col elgg-col-1of2">
<div class="elgg-inner">
<h1 class="elgg-heading-walledgarden">$welcome</h1><br />
$menu
</div>
</div>
<div class="elgg-col elgg-col-1of2">
<div class="elgg-inner">$login_box</div>
</div>
HTML;

echo elgg_view_module('walledgarden', 'Testing', $content, array(
'class' => 'elgg-walledgarden-double',
'header' => ' ',
'footer' => ' ',
));

 

Hope you can help
