Wiki is a website that allows any site users to add, delete, or revise content. This allows for collaborative authoring and ownership, and is different from conventional websites, which can only be edited by the webmaster.
Wikis can be used for community, class, or technical projects that require collaboration.
For example, you could use a wiki to collaborate with others at distant locations on a group article or paper. Your collaborators would log in to TRACS, go to your site, select the Wiki tool, and add their comments or changes to the article. They would also have the ability to add new pages and other additional content to those pages. A wiki could also be used to allow students to write a collaborative assignment without having to be in the same place at the same time.
