John Dunkle and his wife (then girlfriend... didn't know about his brother) started "PorscheList", which became "Rennlist" after Porsche lawyers forced him to change the name. At the time we were all pissed at them for stomping on a really enthusiastic group of Porschephyles... and we were right.
But a part of corporate law dictates that if your corporate name is used without your permission and you don't get paid, ANYONE can use it for whatever they wish. Your responsibility (as a corporation) is to squash it wherever it happens, no matter how wonderful or beneficial it is to your business.
John kept an even keel during that time. He was keeping a server-farm up at his own cost until it got so big he started to ask for donations to keep it up. The response was immediate and sufficient.
Just a little history... I was building my car at that time and had a lot of input from that crowd. Some good, some useless, some... undetermined.
The "Racing" list was the most useful. There were a few drivers that thought they knew more than the mechanics but most responses were useful, as long as the responders hadn't had to much coffee... or other stuff. Frankly, there was lots of conjecture, and much was delivered with "authority". I just relied on the math, opinions from knowledgeable folks, and my gut... turned out ok.
This forum is much the same but with better categories. There is a wealth of information here.
Hmmm. Is this slightly off-topic?

I think not.
