Don’t know why I didn’t mention I’ve been using the Signal android app for many months now. I guess I don’t always associate android with computers…even though it is an OS. Also they have a Linux desktop program that you can use with other Signal users. I started out just with my daughter. Now also my mom. I haven’t really been very vocal about it or pushed it on others. I did ask a mobile medical company to install it, months ago, because they wanted me to text sensitive financial info to them. Which they didn’t do…so I didn’t do either.
I’m bringing it up now because evidently it has recently seen a big jump in users.
