[plug] PGP Sign messages

[Tim White]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

As some of you may  have noticed my messages are now signed using PGP
(Curtesty of Enigmail)
I believe that public keys should be uploaded to a server so that
people can verfy your message. I am wondering what servers people on
PLUG use and how to upload my own key to servers.
Also how does PGP work? Does it create an encrypted hash for the message
or something? Ie. what is to stop somebody from copying the hash and
replacing the message?
Thanks
Tim
p.s. Also, is there any real benifit to signing messages?
