Another new Wave 3 offering, Windows Live Groups is a place where users can set up online meeting places for real-world groups like clubs, teams, families, and the like. Groups consist of you and others you invite via your Windows Live Contacts list. The service makes it possible to share and collaborate in numerous ways, including posting announcements, sending group emails, group chatting in Windows Live Messenger, photo sharing, calendar sharing, and more. It also integrates with Windows Live SkyDrive storage.
