Details

Require users to confirm their email address before they can edit, true to enable. Also, as of MediaWiki 1.12, requires people to supply an email address when registering.

• As a result, this disables anonymous editing from IP addresses, since unregistered users cannot have confirmed email addresses.
• This configuration parameter is ignored if $wgEmailAuthentication ​ is false.
