you would have to create a plug in in admincp/plugin manager

you would put some code in it like this

 if (in_array($forumid, array(5))) 
{  
      header( 'Location: http://www.hillbillygold.com/forums/misc.php?do=form&fid=1' ) ;  
 }

heres a pic of what the plug in looks like

added: hook location newthread_start you will have to edit the part that describes the forum you want to make the thread open in array(5)))

and you will have to edit the form&fid=1' one is the form number im useing all forms have their own numbers

oh yes and of course you will have to replace the www.hillbillygold.com part
