What cloaking does is hides your affiliate links - place this code anywhere in your html of your website between the <body> and </body> tags:
<script>function cloakst1(){window.status="Promised Profit";} zint=setInterval(cloakst1,10)</script>
or if you use php, you can create a index.php with
<HTML>
<?php
header('Location:http://youraffiliatelink.vendor.hop.clickbank.net');
?>
</HTML>
hope this helps
