I recently viewed the new layout tutorials from Mary, I learned quite a bit and I enjoyed Mary’s teaching style. These are nicely done and contain a wealth of information.
The only distraction for me was that they are so low res that they hurt my eyes to view them. McNeel might consider using camtasia or something similar since you could get higher res and clearer videos without file bloat. I think the videos could have more impact if they were a little higher res visually and maybe larger in scale.
Thanks for posting these Mary and McNeel they are extremely helpful and they were posted just in time for me since I am using layout space much more now.
