$find = '<h2 class="forumtitle"><a href="' . vB_Template_Runtime::linkBuild("forum", $forum) . '">' . $forum['title'] . '</a></h2>';
$replace = '
 <h2 class="forumtitle"><div id="scanu"><a title=\'<scanu>' . $forum['description'] . '</scanu>\' href="' . vB_Template_Runtime::linkBuild("forum", $forum) . '">' . $forum['title'] . '</a></div></h2>   


<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>    
<script src="http://cdn.jquerytools.org/1.2.6/all/jquery.tools.min.js"></script>   
<script>   
$("#scanu a[title]").tooltip({   
position: \'center right\',   
effect: \'slide\'   
});   
</script>   
<style>   
scanu {   
background:black;   
color:white;   
padding: 5px 10px;   
-moz-border-radius: 8px;   
-webkit-border-radius: 8px;   
filter:alpha(opacity=68);    
-moz-opacity:.68;   
opacity:.68;   
}   
</style>';
$vbulletin->templatecache['forumhome_forumbit_level2_post'] = str_replace($find, $replace, $vbulletin->templatecache['forumhome_forumbit_level2_post']);
