I will say though, that GT.com was the first forum i ever signed up to i believe and it's the only one i've frequented constantly, and still do. Every other forum has either died or i've grown tired of the community, but for some reason you bastards keep me coming back here.
Compared to other ones i'm on, this is still showing very good signs of life, so i'd say there's another 5-10 years or more in it yet. If not longer.
