mistakes and feedback


In following through the lessons, I have notced several times a move I made that the Mentor said was wrong, but that in fact was either a correct move, (or at the least wrong for a different reason). Example, in the 3rd (or 4th?) lesson about premature attacks, I avoided a mate by moving my black night to f3, preventing Qh2+, yet the Mentor said, wrong, "white would Mate on h2". Is there a way to post comments or feedback on the Mentor?
