Abhishek, thanks for your detailed response and critique. Being a newbie, I understand some of the information you have shared, but I have much to learn to understand all of it. So are I was able to find, download, and install W3 Total Cache. Hopefully it will help. I have not been able to find the part of the Admin panel that will all me to set the option of enabling full content or not, or how many posts to show. Can you be more specific on how to find this?
Thanks again for your suggestions, I appreciate it!
