To Josephbloggs... Fm Gamma You have asked for clarification of my comment.... ALSO.... While the forum has improved by finally showing the name of the person, YOU, using the question mark, a major problem remains. Knowing your identity is helpful to me, but your use of a simple symbol still fails to explain exactly why you are confused. Without written words pointing out the specific problem in the text, the author, ME, has zero information to fix it for you. To actually receive clarification, you must write a sentence explaining exactly what you do not understand. Are you able to pinpoint exactly what you find UNCLEAR? IF you can...I will do my best. But, if you DO NOT KNOW what is unclear, then I cannot help you further. Do you understand this dilemma, Khun Joseph? I am here and willing to help you if I possibly can. Fortunately, now, the TV forum helps me to identify you, the confused one, so that I can respond more constructively. Please provide more information about your confusion. Thank you. Best regards, Gamma
