Microsoft said late Tuesday that its Custom Domains service had officially launched, making it the third Windows Live project to come out of beta. The service allows a customer to use a custom domain name with Windows Live Mail and Hotmail.
Windows Live Custom Domains is a free service, just like other Live offerings from the company. Additionally, with the final debut, Microsoft has launched a new feature called "open membership."
More Windows Live services are expected to come out of beta through the rest of the summer. Microsoft has said over 20 new services are currently planned for the Live platform( Windows Live Ideas).
