Hi :-) I revisited ur page again today Gilles :-)
Why not use : F' U' B' E2 B U F instead of M S D S' D2 M' ?? I think it's easier to understand and more in line with what u show for the corners. And also the part doing the job is symmetric. So P Q P' Q' is in fact same as P Q P Q' which for some will be more logical. Well, anyway showing that breaks the spirit of commutators ;-) Umm, by the way. Flipping one edge on U-layer is much faster as R' E' R2 E2 R' than using F and E moves. I know the beginner solution is not meant for speeding. But even so ... hehe ...
