Peet Venter: Thank you very much. Great work.
Please do not laugh; I seem to have a total mental block regarding LAYERS. Maybe someone can write a step-by-step Noddy language basic guideline not assuming any knowledge. Believe me I have read books, got it right some times but could not repeat my 'success'.... Any one out there hearing my cry for help. Yes, I am BC.
Thank you Ellen, yes a layers article would be welcome.
