[sf-lug] OpenPGP question

So here is the question for y'all. I have multiple email addresses and
would like to have them be digitally signed, using GPG. What should I
do to maintain the signature across multiple addresses? I do not want
to use --gen-key, should I use -adduid or --subkey? I am unsure if I
am even asking this the right way.
