People come to forums for many reasons. While there is no need for unnecessary harassment, a person should have basic knowledge in what they are asking. Posting something like "My engine won't start, what could it be?" is just plain lazy and inviting for a snicker or two.
I've become a heckuva driveway mechanic raising 2 Daughters with multiple used cars. I've had the laptop in the garage with a youtube video going more than once. Have saved thousands of dollars with the help from forums like this, Google & youtube.
