I'm not listing anyone specifically because I don't want to leave anyone out. But, we have a vast array of engineers, physicists, chemists, formulators, computer experts, fleet managers, law enforcement personnel, vehicle technicians, parts people, dealership personnel, pilots, detailers, farmers, truckers, contractors, customer service people, ordinary enthusiasts, and so forth that are wonderful resources for what they do, and contribute a lot. I think that's why we'll often see what some consider weird threads about asking advice on things that have nothing to do with the forum, per se. We have people here that are genuinely willing to help in all kinds of fields, without trying to make a sale.
I'd also like to point out that I have learned something from probably every poster, especially from those with whom I disagree. Everybody here has something to contribute, and I learn stuff from everyone.
As for Clevy, I believe he has spent extended time away from the board before, so I'm optimistic he'll be back.
