   I'm trying to implement public-key message signing with Mailvelope
   software, not with much success so far.  I haven't really done
   signficant amounts of encryption since the 1990's, not much even then,
   and then I used PGP, and not with an email client.
   I realize that I don't have a public key available; I'd like to publish
   it, but there probably haven't been any key-signings nearby.  I'm
   trying to (re-) learn the bare bones of this.  This is my second
   attempt.    The first attempt at signing simply lost my message, for
   reasons entirely unknown.
   I'd like to prove who I am.  At least initially, I though of using a
   Skype call, jimbell887, to talk to a few of the more credible people
   around here.  That will, at least, reduce the level of doubt until I
   can get up to speed on this very irritating software.
   I will put this message, and then have a signed copy of this message.
   I'd like to somehow include a copy of my public key, but as I said, I
   cannot yet figure out how do to that.

   Last night, AFTER I posted this stuff, I tried to post my public key on
   Keybase.   It had not been previously publicized.  I don't know if I
   was successful.  I fully understand that I will have to attend some
   keysigning event, maybe in the San Francisco bay area, or perhaps
   Seattle.

   P.S.  I wanted to sign this message, too, which was edited on Yahoo
   Mail, but the Mailvelope icon seems to not always appear.  How do I
   sign if Mailvelope isn't working at the moment?  <sigh>
