No longer used messages

CLOSED This issue is closed

I believe that all non-English translations of messages marked in languages/messages/MessagesEn.php as do not translate or duplicate this message to other languages should be deleted since they are no more used, such as Newuserlog-create-entry ("New user account") and Newuserlog-create2-entry ("created new account $1").

See FAQ#Old_or_obsolete_messages.
