I actually decided to alter this for my own benefit ...
Look for:
Code:
<td class="thead" width="100%" align="$stylevar[left]">$vbphrase[forum]</td>
Re-place with the following:
Code:
<td class="thead" width="100%" align="$stylevar[left]">$vbphrase[forum]
<!-- RSS ICON -->
<a href="external.php?type=RSS2" style="float:right">
<img src="$stylevar[imgdir_button]/rss.gif" alt="Subscribe to XML RSS for all Threads in all Forums" border="0" />
</a>
<!-- / RSS ICON -->
</td>
And apply the same change to all other cells - what you are doing is moving the RSS image into the previous cell, and retaining the Forum spacings ...
