I was talking to Sapwood at lunch time about making M&T's and the marking out of joints etc and I wondered in this day of machine cut joints and incra jigs etc, how many of us still by habit and need I might add, mark the face side and face edge with the traditional marks immediately after preping and then keep them (or try to) through the life of the piece. I was taught that in wood shop back in school 30 odd years ago and still do it today.
