I have an offer from an individual to purchase a nice PR 5 domain. This isn't a dropped domain. My concern is that if I switch the domain to a new registrar with a new owner I will lose the PR. My thought is to keep the ownership under my registrar anonymous, hoping that it will limit the chances that I lose PR. Can anyone supply me with tips/information on how to maximize my changes of keeping the PR on the site after I purchase it? Feel free to PM me if you'd rather reply that way.
