Dear Agilent,
Anything given free is not appreciated.But,Gratitude,well it is entirely different matter & left to individuals.There is nothing wrong in paying for a peson's expertise.Even in a poor(!) country like ours,Education,a constitutional right of a citizen,is available only at exhorbitant price, including govt schools.So why expect charity from an individual for his expertise unless the person opts for it.Anyway,i am not sure whether you were serious in yr posting.
Let us expect some good tutorials from CV.After all,i have learnt & gained lot of good things from this forum members & that is Gratitude.
This reply is in a lighter vein agilent.I have a nagging feeling that you are a close friend of CV.All the best
