I have created a toolbar that runs on Firefox. You can find it here: [url removed, login to view]
I need to have one just like it for IE7. Currently, my toolbar reports both the PageRank and Alexa Rank for every site that a user visits. The meters can be placed with the other buttons on the toolbar or on the status bar.
Please install the toolbar and play around with it a little. I would like the same functionality for IE.
