Glad to see this car getting another shot, even if it's just to sell and let someone else enjoy it.
The forum is still my number one source for knowledge, but the participation issue is two-fold.
1) This forum prides itself on the best knowledge, and people that know how to use the damn search feature. When the members of this forum have spent over a decade dissecting every piece of these cars and squeezing out every last drop of horsepower, there's little new knowledge to be had, and by using the search feature it means that once the info is out there, the conversation is generally over. We don't like beating dead horses over here.
2) The Facebook page. It's the worst of forums in general in one place under the name of the best S197 message board there is bar none. The page really should be renamed The Mustang Source. I think people find that page first and have no idea that there's an actual forum that was the impetus for the Facebook page. I see that all the time: "Who knows about X?" "There's a 30 page thread on the forum." "Where? I can't find the comment thread." "No, on the actual forum. S197forum.com" "Oh! I didn't know there was a website for this Facebook page! Herp derp!"
