... hey. i looked everywhere i can think to and i can't figure out how to do this. my old gpg key expired a few days ago so i generated a new one. now a lot of people had signed my old key so i want to sign me new key with my old key so it will be trusted as well. how do i sign my new public key with my old private key? any info or pointers i've missed would be appreciatd. thanks, adam.
