Tell a Friend code question

[Jack_mcs]

When I try to use Tell A Friend, only the TO fields are marked as required. If I go ahead and send the email, the subject and body are blank. If I also fill in the FROM fields, the email looks as expected. In the tell_a_friend.php file there is this code:

 if (empty($from_name)) {
     $error = true;

     $messageStack->add('friend', ERROR_FROM_NAME);
   }

Isn't that saying to display an error if the FROM NAME is not entered? If the FROM fields are not required, why is a check performed to see if they are empty? Anyone know how this is supposed to work?
