Your projects are extremely noble and ambitious ideas! I have not managed to read about everything you’re working on right now but am very interested.
I notice you may be using Matrix for your communications - that sounds like a great choice for your purpose, as it allows you to host your own server while being able to communicate with people on the rest of the federated network.
If you would like any more information or support, please let me know. I work as a Developer Advocate for matrix.org, so if there is some issue or (missing) feature you are struggling with, I’d love to be able to help.
You can reply here, or find me on matrix: @benpa:matrix.org
