easiest way:
open admin/functions.php
find in getpostbit section:

PHP Code:

eval("\$retval = \"".gettemplate("postbit")."\";"); 


replace it with:

PHP Code:

 if($post[usergroupid]!=6) {
  eval("\$retval = \"".gettemplate("postbit")."\";");
} else {
  eval("\$retval = \"".gettemplate("adminpostbit")."\";");
} 


then create a template called adminpostbit and make a desing you want to have...
you should copy the original postbit into it and change it afterwards... would be easier
