Eureka! It finally worked. At first attempts, I was not able to enter a URL address. The system allowed me to enter the title of my blog, but each time I entered a letter in the URL area "... blogspot.com", I received a message that it was not available even when I entered my last name. Finally, it worked today, July 12, 2012 and I was able to create my blog! What an experience! It was very exciting.
