Hi,
I don't remember a "Craftsman" Tool Talk board, but there was a Tool Talk board sponsored by some sort of on-line tool store from about 1996 or so. It went through several variations and eventually became "Mark Kw's" tool board.
In fact, it was on Mark Kw's board that I learned of GJ. Haven't been to Mark Kw's site in a few years-not sure if its still up and running or not.
A few of the more regular members at the original "Tool Talk" that I remember are:
John Garner, Ratchet Don, Mr. Pogo, Dale Powell and of course, Mark Kw.
Tool Talk was VERY basic compared to GJ, but was the GJ of its day.
