Hello,

I just started messing around with gnupg and was wondering what I'm 
supposed to attach to the bottom of my email?  Is it the:

-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: GnuPG v1.0.6 (GNU/Linux)
Comment: For info see http://www.gnupg.org
<blahblahblah>
-----END PGP PUBLIC KEY BLOCK-----

part or is it something else?

Also, would I just enclude the key in my signature or what?  (i'm using 
Mozilla 1.0 if that makes a difference).
