Hi Maria... I took a quick poke around and found this article by John Lester about the history of the Braintalk forums:
BrainTalk Communities Inc - John Lester talks about BrainTalk's early days
Here is a link to the new spinal disorders forum. You'll recognize some names there.
Spinal Disorders
I don't know how active it is... When I have a chance, I'll go back and reconnect. I credit Braintalk with saving me from making a serious mistake. When I found them, I had a 2-level lumbar fusion scheduled and had no idea what the stakes were. While I may have been a success, I was clearly making an uninformed decision.
