I have just acquired a PR3 domain at an auction for a good price. The domain has a lot of edu links, including from stanford. However, when looking at it history it looks like it was dropped for a few months in 2004 and then re-registered by a domain brokerage. Since then, it staid in their custody as a parked domain, and recently it was redirected to their main domain. Looking at the PR, like i previous mentioned, it has a PR3. My question is, if those links are still valuable, considering it was dropped. If not, why does it still have a PR 3, considering it had no content and no new links?
