I'm adding an extra "subject line" if you will to my private forums, but I want the 2nd subject to appear in the message. And I want it to be hidden , using e@sy's hide hack.

Encouraging members to reply to find out what we're talking about. Increasing talking. Hopefully..

But so far, I've got the extra subject box added to public_new_topic_form.pl and can make it required.

But how do I call it into public_topic_page.pl
and make it hidden?
