I launched this site about 30 minutes ago and browsing it with Firefox with PR toolbar I get PR10 sometimes PR8... please if you have FF with PR toolbar (search status 1.20) check at my site and tell me I am wrong... http://www.spanishwritingtips.com/ image not touched with photoshop or anything.
I went to it and got a PR0 reading... Not sure why yours showed up any differently.. http://digpagerank.com/index.php?url=http://www.spanishwritingtips.com/
it usually happens on my new site as well while browsing DP...I guess the PR addon stays cached even if you switch to a different tab
Sometimes if you go from say google.com to yourwebsite.com the PR toolbar may not update right away, thus showing an incorrect PR. Click refresh in your browser and it should update.
