I have checked it out. There is so much to read and learn on CZ, at the site you referred me to, other sites. I'm constantly going down rabbit trails looking at new stuff. Sometimes my head hurts trying to take it all in. Sometimes there are so many things to try that I try nothing. It's a strange phenomena to be so indecisive when faced with choices. It's kind've like being hungry but not being able to figure out where or what you want to eat. Thanks again.
