News Corp’s MySpace Internet social network will join the OpenID alliance to begin letting its users take their online identity to other sites and social networks without having to register again.

The move comes after the network decided in May to let its estimated 115 million users globally share their MySpace profile information on some other sites.

OpenID is an open source alliance that, by letting users take one identity to multiple websites, aims to eliminate the need to create multiple user names and profiles.
