As a BBS era kid, I know you’re not trying to simulate the whole thing right now in the comments section. I’d say: you would have done fine, in any era. People talk, they share methods, and you would’ve picked up whatever you needed.

I think it’s just a common sort of nightmare, worrying about being unprepared, dealing with the consequences of lack of preparation.

I recommend the first few minutes of Jason Scott’s The BBS Documentary, for an overview of how people communicated in the pre-internet days. Especially if you imagine yourself a telegraph operator chatting with neighboring stations in the 19th century or something.
