First, thank you for your last statement about your son. THIS was extremely important to me. You go to a car forum to discuss and learn about cars, not to get access to all sorts of objectionable stuff. Keeping this a family type forum is a TOP priority to me.
You also make another good point about how the groups separate out. Thats a good thing too because each group will have its own strengths and weaknesses. Each able to contribute to the community over all in their unique and special way.
