Kai is right, I want the Gcc header to be rewritten when the message
is being sent.  The archiving functionality of Gnus seems to be on the
preparation side, which is OK for most users.

I got header-action.el from
http://www.coling.uni-freiburg.de/~schauer/resources/emacs/header-action.el.gz

It's not immediately obvious to me how to activate it the way I want.
Should it be something like (after loading the lib and adding the
hook)

(setq header-action-list
      '(("Subject:" 
         (".*status report.*"
          (lambda()
           (save-excursion
            (mail-position-on-field "Gcc")
            (insert ",status") ; there already is an archive entry here
            ))))))

I use message.el, so I'm not sure whether mail-position-on-field will
work, or if I'm doing the right thing.

Any help is appreciated.  I am definitely not a Lisp programmer.

Thanks
Ted
