[Discuss] Expired gpg key

[jabr at blu.org (John Abreau)]

It should be noted that if the key is expired, then most likely all
previous signatures on it are almost certainly also expired.

And I'm not sure if the key servers will accept an extension of the
expiration date, at least after it's already expired.If I'm remembering
correctly, I think I ran into this problem several years ago when I tried
to extend the expiration date on one of my keys.
