Good news that this option exists. But too technical for my use.
I hear ya. I’m into computers, have been building websites since the mid 90s, currently run Linux and I’d still have to do a lot of reading on how to set things up. Our internet upload speed is too slow to serve a WordPress website but would probably be ok for html. Email, chat and P2P file sharing would work but video chat definitely not.
Matrix chat server is a good one. I don’t have a cell phone so my wife and I use it to communicate via text messaging aka SMS. She has a cell phone with the Matrix app and I have the desktop app. I created a chat room for us and made it encrypted. It runs on a public Matrix server but this FreedomBox would allow our own, at home device to be the server making it even more secure.
