Thread:Project:Support desk/Enable to export all or a subset of pages by anonymous users in a disabled wiki

My Mediawiki (1.18) was configured for "disable reading by anonymous users" ($wgGroupPermissions['*']['read'] = false), and I want to use index.php?title=Especial:Exportar&amp;action=submit&pages=pageName without login, for direct access, like a open webservice.

There are a setting, plugin or simple hack to do this?
