What is a wiki?

A Wiki could be considered a combination of a Web site and a Word document. It can be read just like any other web site, but any number of people can collaboratively work on the content of the site with no special software and very few technical skills. Besides the ease of editing, it is possible to keep a record of all changes and additions made and who made them.  Each time a person makes changes to a wiki page, that revision of the content becomes the current version, and an older version is stored. Versions of the document can be compared side-by-side, and edits can be removed if necessary.

Some wiki hosts charge but there are plenty of free sites that offer unlimited pages and sufficient storage space for images and documents.
