Wiki service lets you host content-rich websites that users can easily edit in their web browsers. Wiki service is a standalone service that doesn’t require Websites service.
When users connect to the Wiki service, they can create wikis, which can include user-created pages, uploaded files, a blog, and a calendar. All users have personal websites called My Page, which they can use to create pages and blog posts, and upload files.
Users set access permissions for their own wikis, and for their pages and files in My Page. Users can give access privileges to other users and groups on your network server or other connected network servers.
In the Server app, you can choose which users are allowed to create wikis.
For information about working with wikis, pages, files, and calendars, see Wiki Help. To access Wiki Help from any wiki page, click the Action pop-up menu , then choose Help.
