Requiring Email Confirmation to Edit in MediaWiki

From JJBwiki

In order to require users to both register and confirm their email addresses in MediaWiki, set these directives in LocalSettings.php:

$wgEnableEmail      = true; // enable the e-mail basic features
$wgEmailAuthentication = true; // require email authentication for using any email function (except password reminder which works independently from this setting)
$wgEmailConfirmToEdit = true; // Require a confirmed address to edit pages
