Help:Sandbox

Sandbox is a page or a place to experiment with the process of editing. In maximum wiki you can find your personal Sandbox. But in which wiki you won't get a personal sandbox then you have to create it. Like this MediaWiki. Then you have to create a page like:

Foo is an user name.

How to create
You can create your own/personal sandbox here. At first you should go to searchbox then search this. After this you can see User:Your name/sandbox with red colored.
