Stubs are short articles with little or no information. They are created when someone wants to get people to make an artice there, so he makes a short article and puts the {{stub}} tag at the bottom. This will inform people on the page that it is a stub, as well as put the page on the Category:Stubs page. Feel free to expand a stub. Once a stub is more than a paragraph long, please remove the stub tag from the bottom.
