Wiki
Definition
A wiki is a Web site that allows users to easily create and edit Web pages using simple text directly in the Web browser. A wiki can be totally open so that any visitor can edit content, or restricted by a username/password.
Features
A wiki is ideal for quickly creating Web sites, promoting collaboration, and tracking contributions from multiple authors on a single site. A range of free wiki sites offer advanced features including the ability to embed images, video clips and other interactive elements (e.g., polls) on a wiki page.
