Google PageRank for WordPress can retrieve PageRank for every post, and display the PageRank value at the end of the post’s content.
Installation and Usage
/wp-content/plugins/ directoryDownload: Google PageRank for WordPress
WP Turbo is a WordPress Plugin, which can make your blog super fast. WP Turbo can find all static files in your current theme and active plugins automatically and then store them locally with Google Gears on the visitors’ computers. After install and enable WP Turbo, all needed static files will serve directly from visitors’ computers but not your server (to be honest, they need to download them all at the first time when they visit your site). This can siginificantly reduce the page loading time, which may give your visitors better experiences.
And most of all, WP Turbo is developed by my best friend LiuYang. 
Installation
Download, Unarchive, Upload and Active. There is nothing different from any other plugins.
