Testimonial: Thank you for the way you present the information. I am a fan!

I really like having the different stages of the tutorials available for review because I tend to forget a function if I use it infrequently. I used to be current on most functions, but I am soon to be 89 and not so sharp anymore. I appreciate the detail in your tutorials too. Thank you for the way you present the information. I am a fan! – Langston
