[Ring] GNU Ring to replace SMS/Whatsapp

[Stefan Monnier]

I'm looking for a Free system to use to communicate via small messages
with friends.  Ring generally looks like a pretty good option for that,
but I couldn't find a clear description of what happens in Ring when you
send a message to someone who's not currently connected: most of the
tools I've tried so far seem to miserably fail this test.

The description I've found (https://ring.cx/en/about/practical) states:

    A messenger: send text messeges during calls or out of calls (as
      long as your peer is connected).

this seems to imply you can't send text messages when your friend is
not connected: is there hope to fix this shortcoming?  What happens if
you try to send a message when it's not connected (do I at least get an
error back)?  What if he's dicsonnecting right when I send the message
(do I still get an error back)?
