I wish I could believe that tool, but it doesn’t seem accurate. If it is, we are going from a PR4 to a PR7, and while I would be elated to see that, I don’t think it is possible given the strategy we have taken to build links…slow and steady.
If you go to the forums on that site, there is someone debunking the tool altogether, saying it is trying to predict page rank by not even looking at any factors that even affect page rank.
Here’s the forum link:

Here’s another tool that tries to predict as well:

If they are right, we should stay at a PR4, which I see as highly unlikely, though one of our sub-pages will be a PR10. As they say on their site, use it for entertainment purposes only.
