Los Angeles-based MyLife.com, the online people search site run by Jeffrey Tinsley, reports this morning that it has registered its one millionth subscriber to the site. The firm--which was previously known as Reunion.com--said it now has a database of 750 million profiles of people. MyLife's service is used by consumers to find old contacts, and offers its people search services on a subscription basis. Reunion.com merged with the Wink people search engine site in November and renamed itself MyLife in February.
