"A wiki is a type of website that allows users to easily add, remove, or otherwise edit and change some available content, sometimes without the need for registration," according to Wikipedia, one of the best-known wikis.

For more information, you can read Wikipedia's article on the subject.

As public (and semi-public) webspace, a wiki facilitates collaborative work.  For this class, you will use the wiki to collaborate on your final (group) speech, peer reviews of one another's speeches and speech outlines, and as a space to connect throughout the term.
