Thank you very much for your explanations and advice. The idea of using several PLs for 40 days sounds very good but I think they should have a special price for the customers who have the entire library.
The fact that so many of us have so many questions and rely on these forms shows that we need more instructions how to use them. The instruction for each CD is fine when you have one or two, but when you have 16 of them...it's enough to make your head spin. Am I doing right, wrong, what if there is a better way??
It seems like it's a very important tool to use and they should have made it more affordable.
