hmm, i'd replace em with vb code tags:
if you have those tags for marque and so on...

open functions.php

find (in fuction bbcodeparse2)

PHP Code:

if(!$dohtml)  { // kill any rogue html code
    // $bbcode=str_replace("&","&",$bbcode);
    $bbcode=str_replace("<","<",$bbcode);
    $bbcode=str_replace(">",">",$bbcode);
    $bbcode=str_replace("<","&lt;",$bbcode);
    $bbcode=str_replace(">","&gt;",$bbcode);
  } 


and change it to:

PHP Code:

if(!$dohtml)  { // kill any rogue html code
    // $bbcode=str_replace("&","&",$bbcode);
    $bbcode=str_replace("<","<",$bbcode);
    $bbcode=str_replace(">",">",$bbcode);
    $bbcode=str_replace("<","[",$bbcode);
    $bbcode=str_replace(">","]",$bbcode);
  } 


i think it should work
