The site wiki lets members create pages for a
collaborative website. You can contribute and modify content using a
simplified markup language.
When you enter the wiki the page view displays the wiki main page. Click Wiki Page List to display the wiki list.
The wiki page list displays a summary of all pages created for the current site's wiki. Select a page in this list to view it in the page view.
In both views (wiki list and page view) you can create, delete, view details for, and edit a wiki page. However, you must be in the page view to rename a wiki page.
Note: See Customizing a site
for how to switch the wiki on and off for a site.
