I've done that and now I have another question. Why would my main link page directory have a PR but none of the pages within the directory have a rank?
Recently added pages will not have PR. Moreover, google usually updates the displayed PR on a quarterly basis.
2 options. Option 1 : You can check it by installing the Google Toolbar, its available to download at toolbar dot google dot com Or Option 2 : Search for the word "Datacenter PR check" on Google search, there is a number of listed website that you can use their service to check for your or certain Website PR.
