edit forumdisplay.php find:

PHP Code:

if ($foruminfo['allowposting']==1) {
  eval("\$newthreadlink = \"".gettemplate('forumdisplay_newthreadlink')."\";");
} 


Replace it as:

PHP Code:

if ($foruminfo['allowposting']==1 AND ($foruminfo[forumid]!=X OR $foruminfo[forumid]!=Y)) {
  eval("\$newthreadlink = \"".gettemplate('forumdisplay_newthreadlink')."\";");
} 


Replace X and Y with the forumids that you do NOT want the link be displayed..
