Hey, just a suggestion. But I was having problems also with Mike's tutorial. Really funny in some parts (I was surprised at the humor and yet it still kept very much to the point), but the problem I had was with the IK handles. I have not redone the tutorial with the sticky option turned on yet, but I am going to asap. But my suggestion would be to put something on the tutorial information page on the difference in 4.5+ versions. Just something that I would have thought helpful. I even almost dropped the tutorial completely becuause of it. Also though, when I do my IK handles, after I select something else, or deselect the IK handles, they turn a brown orage color along with the joints they were attached to. In Mike's tutorial, his just stay blue, is this because of the sticky thing?

Edit: When I said 'almost dropped the tutorial completely', it was because of the IK handle thingy. Not the quality of the tutorial, that was great .
