I have a question why would you do all that extra coding to put it towards the bottom rather then default top? All you have to do is add valign="bottom" in the div section. Let me show you to put it at the bottom all you have to do is:
Here is normal code within postbit_legacy
Code:
<if condition="$post['signature']">
<!-- sig -->
<div>
__________________<br />
$post[signature]
</div>
<!-- / sig -->
</if>
All you have to do is within the <div> is do this:
Code:
<if condition="$post['signature']">
<!-- sig -->
<div valign="bottom">
__________________<br />
$post[signature]
</div>
<!-- / sig -->
</if>
So to do both mods bottom and your new sig border is:
Open postbit_legacy
Find:
Code:
<if condition="$post['signature']">
<!-- sig -->
<div>
__________________<br />
$post[signature]
</div>
<!-- / sig -->
</if>
Replace with:
Code:
<if condition="$post['signature']">
<!-- sig -->
<div valign="bottom">
<fieldset><legend>$post[username]'s Sig:</legend>$post[signature]</fieldset>
</div>
<!-- / sig -->
</if>
