Microsoft Corporation today is launching the official Windows Live Wave 3 beta.
If I’m correct in saying that wave 3 includes from Microsoft, the latest versions of Live Messenger, Movie Maker, Mail with Calendar synchronization, Writer, Photo Gallery, Family Safety and the Outlook Connector.
These downloads have been confirmed as functional, whether its on a time-trial beta basis or a fully functional beta is still unknown at this time.
happy beta-ing!
