The SlaptiGooglePR Plugin for WordPress adds a Google PageRank column to your Manage Posts subpanel. Unlike other Google PageRank plugins which add a PageRank badge to every post, this plugin gives the blog administrator a snapshot of how every post is ranked without announcing it to the world. Additionally, it keeps track of your overall site PageRank in the Administration Panel header.
Easy as 1 - 2 - 3.
