Wikipedia

Excerpt: "Welcome to Wikipedia , a collaborative project to produce a complete encyclopedia from scratch. We started in January 2001 and already have 41047 articles. We want to make over 100,000 complete articles, so let's get to work! 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."
