[Solved thanks to @tal. See instructions below.]
I’d like to subscribe and occasionally post to some usenet newsgroup like sci.physics or sci.physics.research. It’s difficult! I tried to simply enter “sci.physics” in Thunderbird’s Newsgroup reader, but apparently it doesn’t work simply like that… Even subscribing to news.eternal-september.org didn’t help – I think my understanding of providers and groups is very confused.
Could anyone kindly help?
Since you are asking on Lemmy: “provider” or “news server” is like the Lemmy instance and “newsgroup” is like the Lemmy community except it’s a shared namespace across all servers that carry the group so sci.physics is sci.physics everywhere.
That’s a useful analogy, cheers!
