This is an example of a wiki-like section editable by all registered users. This section allows users to create, edit and delete documents directly on the live site, without access to the full-featured administration interface. It can be used for various types of documents and for various scenarios, including wiki, partner profiles, business directory, etc.
The section is created using the User contributions module, while particular articles are standard documents of the Simple article document type. For more information on this module, please refer to Kentico CMS Developer's Guide -> Modules -> User contributions (Wiki).
