Apology accepted, no problem, we all make mistakes.
Ping lists are maintained by volunteer individual FReepers. Every few years somebody tries to compile a list of the ping lists and who is running each one, but it’s difficult to track, as there’s no central registry of anything.
So you actually have as much “access to ping lists” as any of us, which is to say, best of luck! If you see s comment that appears to be to a long list of people, and certainly if it has a banner or label identifying it as a ping list, just contact the person who posted it and ask them about it.
Gotta run now, have a great evening and weekend!
