Hello Prof and gang, we have finally made it to unit 8 and we have all done very well. I have enjoyed all the feed back and comments from both , my Prof and my fellow classmates. Your comments have helped me to get through this term. I don't think that I could have made it this far without all of you. After this class is over, I am going to continue to blog now that I understand it . Maybe I will be reading some of your posts in months to come. Good luck to all.
