You can see, when you look at the Archive.org record of Extropian posts in their forum, that their subject lines are repeats of the first one. It's impossible to navigate the conversation.

I taught all my visitors at my N54 forums to create informative subject lines as the lines descended. Archive.org only archives some internal posts but not many so the subject lines become the only record of historical account now, other than registering and navigating the impossible-to-navigate Tapatalk hijackers of the N54 system. I'm glad my readers adopted my advice to post informative subject lines.
