Site-wide links? Are you referring to site-wide links in the footer area of site i.e. targeting the sections in the navigation and then are reproduced on every page? I used to do that...had three rows of text links on the bottom of each page that led to the sections in my navigation bar and my site was PR5 took them down and it is PR4 now? I know there are lots of things that will drop a site's PR but what about the above?
