The last part gives invalid html when posts are greater than one in a thread because of the repeated id's.

<vb:if condition="$show['guest']">
<a id="qrwq_5837" class="newreply" href="http://YOUR FORUM URL/register.php" rel="nofollow"><img id="quoteimg_5837" src="clear.gif" alt="Reply With Quote" />  Register To Reply</a>
</vb:if>

I removed them both for valid html. ie

<vb:if condition="$show['guest']">
<a class="newreply" href="http://YOUR FORUM URL/register.php" rel="nofollow"><img src="clear.gif" alt="Reply With Quote" />  Register To Reply</a>
</vb:if>
