YES Exactly...Heresay. Unless you do it yourself you can never be sure,but with time and a few heads of interest we should be able to get most of the answers we need. Unfortunately we need to go on theory at times as no one knows the answer or will not give it away. This ensures at least we can put forward our own theories, ideas and examples forward until we get it right!!!
