Perhaps, but from a purely practical point of view I would appreciate
if Gnus would remind me to add a subject.  Here is an extract from a
folder containing my correspondence with a friend who doesn't believe
in subject lines.  If I hadn't manually changed the subject lines on
the replies, this listing would have been very non-informative.  As
you see, I forgot to do this in the first reply in the last thread.
Having Gnus remind me would be a great help.
