I have done the search as well and it was a mixed review from what I remember, I may do it again and go back and read.
Last night I got out a cursive dry erase board I had bought 2 years ago. Without my help dd did the whole alphabet in cursive - I didn't think she would catch on that quick! The board I have is the old style, very loopy - what I liked about the NAC is the clean, easy, neat cursive and that it wasn't so slanted so it would work with left handers better. She could just use the dry erase board cursive I have and no actual program I suppose - that is how she learned manuscript in the beginning.
