Just one.

That will depend on the participants; some people will sign your new
UID, others won't. It may help if you communicate that you have a new
UID on your key at the signing party.

Make sure the following line is found in your ~/.gnupg/gpg.conf:

keyserver hkp://subkeys.pgp.net

Then, you can search for keys with

gpg --recv-key <data>

where you replace <data> with either the mail address or the key ID of
your correspondent.

After signing the key, please do not randomly upload them; you should
also attempt to verify that the email address of the key you signed is
valid. An easy way to do that is to encrypt and mail the key to the key
owner; the 'caff' script can help you with this. You can find caff in
the Debian package 'signing-party'; it's a perl script.

I'll be sure to repeat this at the beginning of the signing party on

<Lo-lan-do> Home is where you have to wash the dishes.
