I would like to thank to every single teacher from this community. You have no idea how your comments make me feel. I was out of town and I was not able to dowload any recent contribution. I promise I will  try to do it today. Anyway, I also want to wish you a great and excellent Christmas. I�ll go on vacation to see my parents so I won�t be here for about 2 weeks. I will miss you all. So...
