Wikis
From Brock University's Digital Humanities Compendium
Wikis are sites that contain articles created and edited by a community of peers. For the purposes of Brock University Digital Humanities Wikis, anyone with a Brock username can sign in and edit articles. There are standards for formatting and editing with which users should become acquainted before adding or changing articles.
For information on editing Wikis, see the Wikipedia Markup Guide
