[sudo-discuss] changes to Signal

Hi all, I'm a bit confused about what's happening with Signal. I know many if not all of you use it, and I do too. But many of my contacts are not using Signal and are unlikely to change if I ask them to (iPhone people are especially attached to their Message app I find). So does the change (not supporting SMS/MMS) mean that I have to abandon Signal altogether? I can't use two texting apps at the same time can I? I'd appreciate any advice and recommendations. thanks Hilary --- Hilary Naylor, Ph.D. www.a2zed.us Oakland CA
