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 a <a
href="http://wordpress.com/api-keys/">WordPress.com 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(); ?></code> in your
template. See also: <a
href="http://wordpress.org/extend/plugins/stats/">WP Stats
plugin</a>.
Version: 2.1.3
