I still use Forte Agent to access a couple of newsgroups that I've visited regularly for years. They're both dying a slow death and what little traffic there is consists largely of spam and trolls. I have no idea if alt.binaries.sounds.mp3.bootlegs is still active. What sort of bootlegs are you looking for? There are still a few sites available where you can download for free live music bootlegs that are allowed by the artists, e.g. dimeadozen, etree.org. Some require an invite to join. I know for sure that dime is still very active with tons of stuff posted every day in all sorts of different genres.
Is Forte Free Agent still good for Newsgroups?
It's been a long time (over 20 years) since I frequented the newsgroups.
Is Forte Free Agent still the best?
I want to get some classic bootlegs and it's been a great resource in the past.
