If you wish to experiment, you are free to play around on a Test page. However, the Test page is a public page, so if two or more people are simultaneously using the page, it leads to conflict. Instead of using the public Test page you can create your personal Sandbox in which to learn how to use the Wiki and to work on articles you wish to create and contribute to the Wiki. As a first step, you should have chosen a user name and logged in. Whenever you are logged in, your user name appears at the top of any page on the Wiki. See also:
