If i look at your pagesource, i see:
HTML Code:
<!-- sig -->
<div align="right">
__________________<br />
<i>Its not the game, its the people playing it.</i><br />
<br />
<font size="6"><b><font color="darkblue">Sune Johansen.</font></b></font><br />
<b><font color="red">DefianceUO Manager & Developer.</font></b><br />
<br />
<b><font color="darkblue">As you are here, I hope you know the <a href="http://www.defianceuo.com/forums/viewtopic.php?t=544" target="_blank">rules?</a></font></b>
</div>
<!-- / sig -->
A default postbit_legacy will have:
HTML Code:
<if condition="$post['signature']">
<!-- sig -->
<div>
__________________<br />
$post[signature]
</div>
<!-- / sig -->
</if>
Check you postbit_legacy, search for <div align="right"> and change it to a simple <div>
