I am not saying that GeorgeD is willingly misrepresenting his product.
However, the similarity between the product he offers and other previously posted free mats are quite striking.
(at least 2 of the freely released mats come with conditional read-me files.)

If the authors of the other products don't care, that's fine. I call attention to it because I feel it is important for the members of the community to be watchful.
Alot of talented folks spend quite a bit of their time, in order to provide free mats, tutorials, etc. I think the people who use these items have an obligation to be vigilant.
Once again, I am not accusing anyone of willful deception. It is important to be watchful.

Be well.
