BBCode help

[Bilderback]

I havent found a decent solution to add a horizontal rule bbcode.
What I have so far is this and it works fairly well.

<table>
  <tr>
   <td>{param}</td>
   <td width="100%"><hr /></td>
  </tr>
</table>

The usage would be like [HR]text-goes-here[/HR]
and it looks like this.


The problem arises when I have any spaces in the text as seen below.


Does anyone know how I can achieve this type of bbcode without having the text break?
How is it done here at vb.org?
Thanks for any assistance.
