Hello, and welcome to Wikipedia! Thanks experimenting with Wikipedia and for cleaning up after yourself by taking back your edit to the New Deal article. If you wish to make further tests, the best place to do so is the sandbox, because such test edits tend to annoy the users on Recent Change Patrol, even when you quickly revert them yourself. Here are a few helpful links: 
 *How to edit a page 
 *Editing, policy, conduct, and structure tutorial 
 *Picture tutorial 
 *How to write a great article 
 *Naming conventions 
 *Manual of Style 
 Thanks.
