Don't repost on the web, link back instead.
Want to print it out for reference or to show someone? Go ahead.
Make your own tutorials out of mine? Only if you add your own way to use it or new techniques.
Use it to make something? Please link back so others can too.
Want to sell stuff you made using it? You can, BUT you have to link back or tell others about the tutorial so they have the choice to make their own just like you.
