Go to diggIT to download the latest plugin. As of this writing, it is version 1.5. In previous versions, you had to upload the diggIT folder to your plugin directory AND edit a .php file. With the latest version, you just upload the plugin folder to your plugin directory, activate the plugin in your admin panel, and you are good to go.
Once uploaded and activated, the diggIT plug-in will automatically add the Digg icon at the right of each and every post in your blog. You can also use this icon to easily submit your posts. This is a must have for the Wordpress/Digg users out there.
Thanks for the great plug-in Paul!
