Bear in mind as you chase the old timers away that much of the reason others come to a forum is to obtain knowledge from the old timers. Those with the experience pass on to those who don't. Those who don't have the expreience are the lions share of product buyers. They are the ones getting into the hobby and buying shopping carts full of stuff from all the advertisers based largely on what the old timers tell them to buy. Think not? Ask a couple of manufacturers how many containers of product have been sold based on my recommendations. That's $$$ to any advertiser and the only reason they are in business. Other old timers have the same ability simply because they have the knowledge, tell the truth, and convey it effectively. Most all of them have already been named somewhere in this thread. The guy you just helped out the door designs and makes engines. A tremendous knowledge bank wasted, and for what?
