This defines how names are shown when they are displayed in full. The default value, "language", leaves it to the string "fullnamedisplay" in the current language pack to decide. Some languages have different name display conventions.

For most mono-lingual sites the most efficient setting is "firstname lastname", but you may choose to hide surnames altogether. Placeholders that can be used are: firstname, lastname, firstnamephonetic, lastnamephonetic, middlename, and alternatename.
