Corey & DJSquared,
Thanks for testing!
"It says I have 0 backlinks for both Yahoo and Google, which I know is definitely wrong."
- you can just click on Backlinks result (bold green numbers) in the table: links lead to
http://www.google.com/search?q=link:YourURL and
http://siteexplorer.search.yahoo.com/search?p=YourURL&bwm=i&bwmo=d&bwmf=u which is the way to check your indexed backlinks directly. Of course you may have a lot more inbound links to your site but they are probably not indexed. If your check your site inbound links via Google webmaster tools you might find many of them yet they are not included in Google search index.
Just as an example - if you check how many Google backlinks Yahoo.com has, you'll be surprised that there are only 5,590.. of course there are tons of links to yahoo.com but only a fraction is in Google index
"A recommendation: Custom PR Checker graphics.
There are so many PR checker websites that use a graphic that looks very similiar. And maybe a better looking favicon."
- thanks, i'll be working on it, my designer skills are next to nothing
"An error/problem: Layout.
Here's a link to a screenshot of the site:

As you can see the right sidebar is cut-off and there is no way for me to scroll there and look at it. My screen size is 1024 x 768."
- thank you, really appreciate this issue report!! will fix it asap
