Friday February 13th,
we just have learned that our dear and genious friend Jean-Michel Cour has passed away this morning.
Jean-Michel was the genuine inventor and founder of TUNECHARGER, he was also a part of wisdom.
Jean-Michel was always the friend who reconciles, the adviser who pacifies and the hands that cure.
Those who knew him may witness how he restlessly spent his time to make good around him.
Jean-Michel, your place is undoubtedly among the fairest of the fairest.
Have a nice rest, my old dear friend.
