I really dont think that he joined the site in 1969. Considering that 1. The Internet as we know it didnt start till 1980's and 2. IPB was not around back then either.
Let alone that fact that PCs as we know it didnt hit it till 1980's as well. So yeah join date was a bit of a exaggeration.
i think the join date may be a joke, the internet wasnt available to the public until the 90s lol so how on earth could he join a non existent forum in the 60s
