@771c7916 Use simple xmpp protocol for all that. Mailing, chatting, creating some network communities, building pages and so on. It's a very versalite thing. Can be used without any problems. And years ago it was commonly used for that. Why not today? Because every corpo need to have their own, closed, incompatible, proprietary and preferably paid one? Ehh.. we already had all the tools and pieces since years for creating a normal user friendly networking. We are sadly way to stupid to use it. 

 @f275d986 there are many more protocols out there than just XMPP and Signal, what about say Nostr, WebRTC  and others? So which one would it be then? That is very likely why we have so many - nobody ever made any decision for everyone, so all platforms went their own way. That really needs to change to at least have something to interconnect. 

 @771c7916 What I meant was an example of some of the oldest one from the IRC times. WebRTC is a piece of unsafe in many ways, privacy unfriendly junk.
