Looking for a simple self hosted chat system for non technical end users. We got everyone off FB messaging to sms but the android peeps have old devices that have the blurry low res image issue receiving from iPhone users. I have a Synology nas and have tried syno chat (clunky) and rocket chat via docker (too many bells and whistles and overly complex onboarding of end users) Suggestions? Anything that can spin up in a docker instance, I will try. #selfhositng #chat
