More than that, it checks if all fields filled correctly, and also makes sure to avoid comment duplication, and has flood protection capabilities as well.

Probably one of the best ways you could spice up your WordPress Blog with AJAX; readers love it! Must see for yourself.

This plugin works well in all major Web browsers, and uses discrete AJAX. That means if JavaScript disabled, it’s using the original comment posting method.

This plugin will allow your readers to get email notifications when comments are left on a post after their own. The install is very simple and does not modify any WP core code. As well, it’s future-proofed to work, as is, with the next version of WordPress without your needing to upgrade the plugin.
