The Monday before (4/13) the Lab released Name Changes. (Ref)
In 2010 the Lab took away user selected last names. Now they are bringing them back for Premium members willing to pay US$39.99 (or L$10,140). All the details can be found by clicking Ref above. There is a FAQ linked to from the article. It will answer most of the questions about names and what you can change and how often.
