Members can see how many are subscribed to their thread

You can do something like this: create a plugin using hook showthread_complete and this code:

if ($thread['postuserid'] == $vbulletin->userinfo['userid'])
{
    $res = $vbulletin->db->query_first_slave("SELECT COUNT(*) AS count FROM " . TABLE_PREFIX . "subscribethread WHERE threadid = $thread[threadid]");
    $subscribed_count = $res['count'];
}

Then edit the SHOWTHREAD template and use $subscribed_count where you want the count to appear, maybe like:

<if condition="$thread[postuserid] == $bbuserinfo[userid]">
$subscribed_count subscribed to this thread
<if>
