Adding email addresses to a key

[sweetser at TheWorld.com (Doug Sweetser)]

Hello:

I registered for the key signing party on Wednesday at:

        http://www.blu.org/meetings/2003/09/keypartyregister.php

That was way easy: an email address, then one button click.

The thing about that key is it has only one of four email addresses
that I commonly use.  As I recall, there is a way to keep the key the
same, but change this meta-data.  Could someone remind me of what
those commands are for gnupg?

Thanks,
doug
