Replying to messages with gnus

[Bob Hilliard <hilliard@flinet.com>]

     In my .emacs file I have the following variables set:

; To send a blind carbon copy of every outgoing message to yourself,
; set the variable `mail-self-blind' to `t'.  (from emacs help_info)
(setq mail-self-blind t)

; To add a signature to messages:
(setq mail-signature-file "~bob/.sig")
(setq mail-signature t)

     When I use gnus to reply to a message, these variables are not
recognized, although other settings from my .emacs _are_ recognized.

     These settings are used when I use emacs to send mail.  Can
anyone suggest what I should do to make them work in gnus?

Bob
