Welcome to Wikipedia, a collaborative project to produce a free and complete encyclopedia in every language. We started in January 2001 and are already working on 6,819,266 articles in the English version, with more being added and improved all the time. Anyone, including you, can edit any article right now, without even having to log in. You can copyedit, expand an article, write a little or write a lot. See the Wikipedia FAQ for more background information about the project, and the help page for information on how to use and contribute to Wikipedia.
