Gerald Frenette, New Brunswick, Canada

Being a survivor from a major stroke, a few years back, and 81 years old, my activities are somewhat limited. But then a few months ago I started to get interested in Sudoku and it was difficult at first with all the web information, Then I ran into Sudoku Professor and it all changed. You are very good and in just a short time this has become my best hobby. I find it keeps my thoughts clear and every puzzle it now a nice challenge. Thank you so much.
