Hi John, I really want to thank you for all your thorough explanations.

Yes, I did upgrade, and I have successfully sent in my public key to
keyservers using OpenPGP key management in my Enigmail, although I still
couldn't export the key to keyservers using my gpg4win GPA (getting the
same message: "no plugin available for this protocol") -- but you don't
care about the GPA -- nor using the command line. I really don't know
why. If someone else can explain why the latter two mechanisms don't
work, please do. Thanks.

Thank you John for your patience with my beginner frustration. (And I
wasn't trying to hide my keyID, but just too lazy to type it.)
