I am using Firefoxes SearchStatus and it says that my forum has a pr of 2/10. however,Google toolbar says its unranked....
PR can fluctuate depending on which data center you're connected to. Check out: iwebtool.com/pagerank_checker They pull results from over 30 different servers.
I also have both searchstatus and Google toolbar, and the PR shown there is not consistent. I found out that the PR displayed in Google toolbar is not real-time and is still showing the one with the last tab I viewed.
check it from here http://digpagerank.com/ that will help u to see ur pr from all the data centers some times different data centers give u different pr
