@Mozilla: I think it is available once in your domain registrar. Once you registered a domain under your name it will become available to the pubic. When I registered my domain at Godaddy, it automatically shows up at Who.is ( you can also use who.is to check for available domain names). You can however choose to hide your domain information from the public if you choose to but for a small fee. I found an option in Godaddy where you can purchase that kind of privacy. I hope that helps.
