- Apr 11, 2013Thank you so much for the feed back.This is surely an art.I have visited and read some of the books available and am getting wisened up.I will do some studying and lurking around to see what all I can pick up and ask questions to you professionals when needs be.
I realize that I knew very little about this process and am willing to learn.It should be a fun experience .
Thanks again for all and any feed back.
