Dear Jun, thank you for your note. Yes, Allison Blakely’s book is truly useful. I am reading it slowly. It is packed with information and at times I have to go back and reflect on previous pages. By the way, I cannot work the link function above the text box. I did the copy and paste application, the URLs did not light up, so I surmise they were not live. However, I was able to have it accepted and put it in the text box below your message as an answer. In the menu above I received an error message though. When I went back to reply to you, again the previously submitted page disappeared. Now, I shall again try the copy and paste below this note. I shall see if it works even though the URLs will not be live. As you said, you can follow the links anyway whether they are clickable or not. Thanks again and best, Eva.
