The sandbox is a place where you can test editing a page. It is really simple. Just click on the edit link at the top of the page and write your text into the form. You can write plain text. Don't mind about the formatting. This can be done by others later. Just one hint: you get headlines using double = signs. Afterwards click save page and you are done.
