Hi there! I just stumbled on this list, it seems like the project just started, yes? I was a frequent BBS user in the 90's and still "call" (by telnet) BBS' from time to time, most frequently a BBS in Finland (it's on a VPS these days so I'm not sure it's actually hosted _in_ Finland anymore) called Haciend El Bananas. I recommend it, it's focused on ANSI art and bullshit-chat and there might be some files to download also but I'm not so interested in that anymore so I don't keep track. I use Syncterm to call those boards that use MS-DOS character graphics, it works pretty well. Regular *nix shell telnet can connect too but the ANSI will look like vomit.
Fidonet isn't the only BBS echo active out there, on the top of my head I can remember Agoranet, Retronet and Zeronet (for the elite! ;)).
I didn't have access to internet when Usenet was still a thing so I'd also be interested in some Usenet/UUCP revival. I check som NNTP news from time to time but the traffic is real low nowadays if you go outside the binary groups.
Outside household python scripting I can't code but I can contribute something else eventually I hope.
Cheers, Ola
