I know that if we start charging for membership that new knowledge will stop coming in. I know that if I was developing products for a car and found a place that charges membership to post I would take my offers someplace else (fordcontour.org). I know that many new members will do the same. Having been around the site for a year though, I would pay for the membership, although I think that our new aftermarket parts would fall drastically (lower than they already are).
