How to avoid "Empty header for Subject; enter value:"?

[Marius Hofert]

Hi,

Is there a way to tell Gnus not to ask for a subject ("Empty header for Subject;
enter value:") if there is none specified?

Although I understand that this is 'good practice', I was wondering if there is
a way to suppress this message since I have to type in my password for signing
the email and I am so used to that, that I sometimes accidentally type it in
when asked for the subject (of course I delete it then, but I would rather not
be asked for a subject).

Cheers,

Marius
