I am not sure everybody knows about Domain parking. Just like to share what I came through while surfing. According to Wikipedia, "Domain parking" refers to the registration of an Internet domain name without that domain being used to provide services such as e-mail or a website. Through domain parking, it seems we can make money. I came to know this through one website called SEDO. Visit the site once to know more. It claims if we have registered domain names, but they are not currently being used, then domain parking is a great way to put those domains to work, earning revenue. SEDO claims that they are offering a good revenue sharing.
