This is a list of frequently asked questions about using and contributing to Wikipedia. For factual and other kinds of questions, use the search box or the Reference desk. If your question is not answered on this page, use the search box above, browse the various FAQ pages or perform a search on the Help desk archives.
You are required to have a Wikipedia account to create a new article - you can register here. (To see other benefits to creating an account, see Why create an account?.)
The best way to find out is to look at the deletion log for reasons (type the exact name of the article in the Title box, including the capitalization you used). For more information, see: Why was my article deleted?
You move the article using the "move" button (to the right of the "edit this page" button). You must have an account, and it must be at least four days old and have made ten edits to move pages. If you are not an autoconfirmed user, the move is controversial or the page you wish to rename is move protected, visit Wikipedia:Requested moves.
A username cannot be deleted. If a username was deleted, all the edits made by the user could not be properly attributed. You can, however, change your username, and request that your userpage and talk page be deleted by placing {{db-user}} on both pages.
Wikipedia is not a printed encyclopedia. If you are asking this question because you wanted to cite a certain revision of Wikipedia articles, you can see the page Citing Wikipedia.
Almost all articles on Wikipedia are written by multiple editors, not just one. If you click on the "history" tab on the top of an article, a list will be displayed of all the contributors to the article. If your purpose is to cite Wikipedia, see the question above. Also see Who writes Wikipedia.
There is a third party site, not maintained by Wikipedia, which currently allows you to view page hit counts since December 2007. Toplists are available here.
