Yahoo dropped their special interest groups a couple of years ago. People began flocking to the facebook sites but the rub of it was you can't archive stuff on the facebook sites like you could on the Yahoo sites, and all of the data from them was lost. If you have read anything on Stunthanger by Andre Ming, he was the owner of one of the largest groups, aa vintage enduro motorcycle and ISDT enthusiast group called VINDURO. Stunt hanger isn't and never was a part of the Yahoo Groups. It belongs to Sparky lock stock and bagel.
