Ive got a forum where all outgoing links are like: http://www.theflickzone.com/ext.php?ref=http://www.example.com/ Code (markup): And now http://www.theflickzone.com/ext.php has become PR4. Is this right?
The PR reported by the Google toolbar is notoriously unreliable. It doesn't mean much. However, you may be leaking PR to ext.php. Make all your links to ext.php rel=nofollow and it'll fix this problem.
