Where can I find a commutator tutorial?

[malcolm]

I can do corners with commutators, but always end up with many misoriented ones, it only seems to work for me when there are just 3 left to be solved. Also, i am useless at commutators with edges. Is there anywhere i can find a good tutorial?

Joel's site has one.

How about one that's right on this forum? http://www.speedsolving.com/showthread.php?t=169

These are helpful, but focused more on corners, i can do them well now. Edges i can kind of do, but could be better. Any specifically related to BLD?

Edge commutators are the easisest thing since sliced bread.
Just take this one:
[M D' M',U] => M D' M' U M D M' U'

Thats basically it!
