3 Plugin Name: Akismet |
6 Plugin Name: Akismet |
4 Plugin URI: http://akismet.com/ |
7 Plugin URI: http://akismet.com/?return=true |
5 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://akismet.com/get/">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><?php akismet_counter(); ?></code> in your template. See also: <a href="http://wordpress.org/extend/plugins/stats/">WP Stats plugin</a>. |
8 Description: Used by millions, Akismet is quite possibly the best way in the world to <strong>protect your blog from comment and trackback spam</strong>. It keeps your site protected from spam even while you sleep. To get started: 1) Click the "Activate" link to the left of this description, 2) <a href="http://akismet.com/get/?return=true">Sign up for an Akismet API key</a>, and 3) Go to your <a href="admin.php?page=akismet-key-config">Akismet configuration</a> page, and save your API key. |
