If you edit the plugin "Disable Smileys" in your Plugin Manager,

Find the line:

$bfind = '|<img src="[/forums/]*images/smilies/[\w -.]+" border="0" alt="" title="([\w !@$#%&*()+-=?<>\';:]+)" class="inlineimg" />|';

And add a subforum like this:

$bfind = '|<img src="[/forums/]*images/smilies/subforum/[\w -.]+" border="0" alt="" title="([\w !@$#%&*()+-=?<>\';:]+)" class="inlineimg" />|';

Then the mod will only disable the smilies in that subforum and ignore the regular ones.
