The Windows Live team recently released a new service called Windows Live Community Builder. With this service, you can offer your community members, whether for business, non-profit, or anyone, customized versions of Windows Live services like Windows Live Search, Windows Live Photos, Windows Live Contacts, Virtual Earth mapping, & Silverlight technologies. The service also includes the features of Windows Live Admin Center, which brings Windows Live Hotmail, Live Calendar, Messenger, Spaces, & SkyDrive services to your users branded with your own domain name. For a killer example of the Community Builder in action, check out The Group Inc. Real Estate's website. Built with Live Services, the site features map-based property searches. A bunch of other mashups are listed here. And if you want to get into the nitty-gritty of the Live services that Community Builder uses, this PDF has a color-coded chart showing the platform's web controls, service APIs, and data.
