I have a newsgroup subscription, but a lot of the posts are obfuscated (confused titles that don’t make sense) so you can’t read the post headers like you can in (say) lemmy or reddit (spit! ) . So I also subscribe to a nzb provider (makes sense of the obfuscated) .
In terms of money it’s not too much - like £20/year.
The nzb provider searches the usenet then your newsgroup host downloads what you want.
I’m probably not very clear, and this has been a learning curve for me, but if I can help I will, just ask. It’s good fun - especially when it works!
Edit: too many ‘buts’
I’m using nzbgeek to find stuff. Then put the links it returns into eweka - a usenet provider. I’m new to this, so I’m just dipping my toe in to make sure it works. Currently it does but I’m sure there are better deals if you look around.
