There are many tutorial systems out there for Worldbuilding. You are free to post your favorite one, but make sure no one else has posted it.
You are free to post your own tutorial as well, but DO NOT call it "Worldbuilding Tutorial". That can get easily confusing for others. Give it a special name to help differentiate yours from others, ex (mine): Madness Worldbuilding
So when I post a topic, I'll probably do "Madness Worldbuilding #14.1 - Copper"
In the post, you can do the full posting (up to the limit for a single post) or do an excerpt with a link to your tutorial. Try to reduce the amount of pictures you use.
