Thanks, Greg, for the wonderful course.  I have found these videos to be illustrative and enlightening.  I still struggle with range, but I am working on it, and my tone has improved significantly.  
I decided to revisit some of the first instructional videos, and I highly recommend this review to members who have been working the course for a while.  I found a new perspective after revisiting these early videos.  When reviewing the beginning videos, you mention something called “many lemon.”  I have not seen this item yet.  Is this a topic coming later in the course, or has it not yet been posted?
Thanks,
Eric
