Help:Random root page

Randomrootpage (Special:Randomrootpage) allows the display of a random root page a wiki.

The regular random link generator (Special:Random) is not suitable for some wikis or namespaces where utilising subpage hierarchies (such as Wikibooks). So this function can be used as a substitute—for example, it can be used to show "random books" in Wikibooks, instead of random pages). The function can also be set to display that root page within a specific namespace. In a namespace where there are no subpages then the functionality is the same as Special:Randompage.

Usage
There is currently no functionality that provides the random display of a subpage.

Some wikis utilise this in the configuration of their sidebar (Mediawiki:Sidebar).

History
This functionality used to be in Extension:Randomrootpage though was merged into core in Mediawiki 1.27.
