Please see on, because from experience this is the most actual Google Page Rank for me: http://seopen.com/seopen-tools/pagerank.php Yes I had page rank 4 before, but never in my life on any of my sites I had page rank 5, even I am working as Webmatser/Webdeveloper more than 5 years
Before one or two hours, and now I wait to be updated to all other google page rank applications like seoquake, etc ....
Yes I know, but now it is even on DMOZ.org 5, and before half an hour it was 4. It means they need some time to update itself You can see even in google dmoz directory now it is 5 http://www.google.com/Top/World/Srpski/Kompjuteri/Internet/Chat_i_diskusione_grupe/
Dear Mate, I have gone through it. Google toolbar is more official or SEOpen? Well, i had checked in SEOquake also, shows me 4. Forget it for now, hopefully you will get 5 in G TB too. Best of Luck.
