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