Thank you very much, that got me exactly what I wanted. One last question, using this code..
<td>
<a href="#">
<input type="image" src="$stylevar[imgdir_misc]/poststake.gif" alt="post_stake" />
</a>
<!--
<a href="#"><input type="image" src="$stylevar[imgdir_misc]/poststake.gif" alt="post_stake" onClick="javascript

opUp('placestake.php')"/>
</a>
-->
</td>
...how can I write something into that to make it, once clicked, to automatically create a new thread in a certain forum? Anwsers or documentation links would be greatly appreciated.
