I still a member there, haven't posted in a couple years. I joined the original Drydock around early 97 maybe late 96. That was on the " inside the web" message boards and was part of a bigger Mopar community, I think based in Detroit, could have been Chicago. The Drydock was just a page on that board and became their most popular. At some point they changed servers but eventually disappeared. Scotts Drydock is a spin off of those original boards and is now ten years old. The link you posted are the remnants of that original board now owned by Alpha mopar.
Very good times on that board, I met a lot of knowledgeable people of which most of have removed themselves from the BS of message boards
