Plugin Name: Akismet
Plugin URI: http://akismet.com/
Description: Akismet checks your comments against the Akismet web service to see if they look like spam or not. You need an <a href="http://akismet.com/get/">API key</a> to use it. You can review the spam it catches under "Comments." To show off your Akismet stats just put <code>&lt;?php akismet_counter(); ?&gt;</code> in your template. See also: <a href="http://wordpress.org/extend/plugins/stats/">WP Stats plugin</a>.
Version: 2.3.0
