Requesting the following addition to the robots policies of the Icelandic Wikipedia:
$wgNamespaceRobotPolicies = array( NS_TALK => 'noindex', NS_USER => 'noindex', NS_USER_TALK => 'noindex', NS_PROJECT_TALK => 'noindex', NS_FILE_TALK => 'noindex', NS_MEDIAWIKI_TALK => 'noindex', NS_TEMPLATE_TALK => 'noindex', NS_HELP_TALK => 'noindex', NS_CATEGORY_TALK => 'noindex', );
That is to say, exclude pages in userspace and talk pages from indexing. Users should still be allowed to control userspace indexing so no change to $wgExemptFromUserRobotsControl is requested.
