.blend tut

I am posting this here because it didn’t get moved from Blender general
this is a link to what I have been working on
I am trying to make a Blend file that has examples and links to tuts that might answer some of the questions I see asked repeatedly at Blender general.
If any one is interested I would like some help
take a look at the basic training file mentioned in my link I like how that is set up. it shows the basics I would like to show some examples of stuff that’s a little more complex.
I want the file size to stay small
I want the file set up so people can play with the set ups
I want the file to include images of settings, and renders of the scene with those settings that way you can tell what you might have changed as you play with different settings.
