Signature File in CC:mail

["WALTERS, DONNA" <dwalters@IMAIL.VALPO.K12.IN.US>]

           Our email is CC:Mail version 2.  I use a Mac.  Does anyone else use
        this?  If so, how do you get CC:Mail to copy or to default to a
        signature line with your address each time you post?

           And those of you that always include a "quote" after your name...is
        this a purchased add-on or how do you do that?

           Thanks for helping a "newbie!"  Donna
