Mike,
Is there now or is there a future plan to include the ability to send
SMS / Text messages to phones?
It has been discussed, but I don't think there's a plan.
One issue is that there's a cost for sending them, so it would have to be a paid group, or paid memberships, or something (see Mark's reply in the second message of that topic).
That topic is now locked, so you'd have to start a new one to bring it up again.
