My signature and its (missing) space

Hello,

Everybody tells me that my signature separator is "--", but it needs
to be "-- ". When writing my mails / my Usenet articles, it seems to
be "-- ", as I can get one space further on the right of "--", which is
something I cannot do on the other lines of my signature.

My signature separator is
(setq gnus-signature-separator '("^-- $"))

Do I have to modify it to make it as these persons want it to be?

Thanks.
