wi·ki

(wĭk'ē) n. pl. wi·kis
A collaborative website whose content can be edited by anyone who has access to it.

A wiki allows anyone to edit, or delete content that has been placed on this site, even other authors work. It has been found to work very well, surprisingly, since contributors seem to be more persistent than vandals. It helps because when you find info on the Internet that you know is incorrect you can quickly, click Edit, and fix it.
