So, I've generated my GPG key pair. Created a subkey for signing and a subkey for encryption. Exported the whole thing, removed my master key pair to a secure place, re-imported only the subkeys. Now, I take my fingerprint and passport to a signing party and folks verify my identity and go pull my key off a keyserver, sign it, and upload it back to the key server.
After refreshing my keys I now have their signature on my private subkey?
Does that mean upon receiving a signature from someone else I need to go get my master key pair and sign it with my private subkey or?
If I lose my laptop before transferring signatures to my main keypair they are lost forever?
