Razasharp,
you need to input 3 fields - lets name them subject1, subject2 and subject3.
Then you'll need to edit the php script which processes your forum to set the subject

PHP Code:

$subject = $subject1 . " " . $subject2 . " " . $subject3; 


I would put some validation in there, too, to make sure they entered all 3 fields.
