When searching for an artist you get a link to create it if it doesn't exist: http://musicbrainz.org/artist/create?edit-artist.name=Artist%20Name
In this page, the "Enable auto-editor privileges for this edit." checkbox is unchecked. Adding an artist is always an auto-edit (right?) so this seems a bit confusing to me, as http://musicbrainz.org/edit/14568934 became an auto-edit anyway.
This is harmless, but a bit weird.
