About Windows/Linux I believe you. Nevertheless, there are only a few people on the IRC/Matrix and they have not written anything there (although I have written). About NNTP, there is the RFC documents relating to it, and some NNTP servers. Some are Usenet, although the NNTP server for my project is specific to that project. You can use any NNTP client software to access it (or just operate the protocol directly); some email software can also use NNTP.
