You certainly seem to be making a nice effort for those who wish to learn the basics. I was surprised to see the rejection left by the mod of that famous group - it seems with tutorials, the rules exclude every and any thing, while when it comes to work derived from other's efforts, it is supported - notwithstanding the derived work is released without code or even the courtesy of attributing credit to the original work. I fail to see a lot of the sense in many things but then again I am not very smart ;-)
