Windows Live Domains has been released for a while and I haven't got a chance to play with it until recently; Anyhow, I changed my peterzheng.com email hosting to Windows Live Domain and test-drived it for a while. It is quite sleek. To help everyone else to get a feel how it works, I turn on the "open membership", so anyone can register an email box on peterzheng.com. No guarantee that I am going to keep it forever
