rabbitoid: Thanks, I see it now.

In playing a game of Dameo the site allowed, in fact insisted that I make a backwards capture of a pawn with a pawn. I playing white had a pawn on a5, my opponent moved to a4 and i had to take it moving to a3. Is this a bug or a valid move? It isnt clear to me that pawns can move backward, it doesnt normally happen in checkers.
