Wikipedia:Main Page/contribute

Wikipedia is the largest encyclopedia ever written - and it is written and maintained by thousands of volunteers. Listed below are some ways you could contribute - there are a wide variety of tasks. If you've never edited before, you should check out the Tutorial, and if you sign up for an account, you'll get access to some helpful editing tools (under Preferences), and make communication with other editors easier.

Basic tasks
 * Wikifying articles from Category:All articles that need to be wikified. Before you start: Cheatsheet, and look at other articles' formatting and linking.
 * Revert (undo) Vandalism - from pages on your watchlist, or from Special:RecentChanges. When you get some experience, try Recent Changes Patrol for advanced tools and more complex issues around responding to Recent Changes.
 * Learn how to cite information in an article, then head for Category:Articles lacking sources. Find an article of interest, and look for sources.
 * Consider looking for WikiProjects on topics of interest, to find work that needs doing.
