Google Toolbar PR is being updated today. I was reading Digital Point Forums and found out about this update at this thread.
Daily SEO has moved from PR 5 to PR 4 due to the summer vacation I have taken, and not working on the site.
I have new projects for our site, and it will be updated more often.
Even though toolbar PR’s value is open to discussion, I hope your sites have gained the PR you have well deserved.
