"The VE wiki continuously monitors and measures how well structured are the groups that collaborate on its pages. If needed, it can also be used to maintain collaborative work within certain levels of equity and evenness. Thus the tool serves a double purpose. On the one hand, it can be used as a monitoring tool, for understanding how collaboration is structured. On the other, it can be employed for adjusting collaboration along particular parameters desired by the instructor or site administrator. The wiki is built around the MediaWiki platform, through which content can be edited by any user, including non-registered ones, all changes are permanently stored, and access to information that was edited or added is instantaneous. In addition, all pages come with “talk” areas, which allow discussions and interactions about the editing process. This makes it well adapted for collaborative work, especially of a textual nature."
