DC2NET Links

Hi.
I’ve had a brand new domain for about 6 months and in that time it was used for a site i’m developing, Anyway the site is still in development now but it’s nearly ready and I noticed yesterday that the homepage and one other page has a google PR score of 3/10. I’m not knocking it because I’m really pleased but im just curious how this could be because I haven’t even started link building yet and the site not even finished. Any guesses would be great. As the site’s not ready, I really don’t want to send people there which is why I haven’t added a link but if you really want to see it send me an email and ill send you a link.

Has this happened to you before?
