Pagerank

I've recommended the Googlebar plugin before. One thing it is missing is the google pagerank. This is a popular feature, strangely missing from Googlebar. However, this page from the Googlebar site explains in more detail why it's not available, as well as providing some links to plugin sites that do provide a pagerank. Note that they do voice some privacy concerns, namely that you are in effect sending your IP address and your entire browsing history to every site you visit.
