Do you know if it's possible to allow registered users to view particular special pages, but prevent users in the banned user group (made with $wgRevokePermissions) from viewing them? I'd like for all users to have access to RecentChanges, but not for the troll who has been stalking it. I don't think there's a need for anons who can't edit to read it.
