I've updated the Akismet plugin to use the BasePlugin and tighten the security. You need to be running the latest Mango's version (1.4.3) to be able to upgrade. Akismet comes built-in with the CFFormProtect plugin, but this plugin is an alternative if you only want to use Akismet.
To upgrade or download, enter this address in your administration Plugins section: http://mangoblog-extensions.googlecode.com/files/akismet_1-2.zip
