Great

now, go into the manager, top menu Elements/Manage Elements/ then click the Snippet tab.
Choose New Snippet. Give it a name, make it something easy to remember, ex: CommentText
Copy and paste the code below into the content area, making sure there isn’t double start and end <?php ?> tags (easiest way to ensure no duplicates is to delete the ones that are in the form before pasting in the code below):
<?php
/* CommentText
usage: call uncached
[!CommentText!]
*/
$output ='';
if(!isset($_SESSION['webValidated'])){
// if the user is not logged in, show this message
$output .='<p>Please Login to post comments</p>';
}
return $output;
?>
Modify this area of the snippet code to change the message shown:
<p>Please Login to post comments</p>
Click Save, then open your Comments chunk for editing.
Add the following snippet call to the top of the chunk content above the container <div>:
[!CommentText!]
Your Comments chunk will then look similar to this:
[!CommentText!]
<div id="commentsAnchor">
[!Jot? params.....!]
</div>
Click Save, and then check the page. If you are not logged in as a web user, the message will show above your comments.
