Richard, Hello and thank you for your generous support. It has helped many of us. Hoping to repay your generosity, and to DIY my own system I have sent check #2366 in the amount of $54 to your home location as requested. I had ordered your DIY book 45 days ago. I have not received any book or any acknowledgement of funds received. I have emailed you twice asking for a response. Nothing. I hoping you are in good health and will respond here, or to my emails. Thank you//Alan
