Art wants to register a domain name and be sure that he owns the website. Leo says that is important. He won't want to let a web host register it for him because they could end up owning the domain. Then he'd have to try and pry it from their clutches. So Art should go to a domain registrar first, get his domain and then he can go to a webhost and have them set up his site. This way he will keep the domain ownership.
