WP Wizard Cloak cloaks, tracks, and shortens your links. Turn long URLs into your-domain.com/link.
Either: - * Upload the plugin from the Plugins page in WordPress * Unzip wp-wizard-cloak.zip and upload the contents to /wp-content/plugins/, and then activate the plugin from the Plugins page in WordPress
For best results enable Pretty Permalinks from the Settings -> Permalinks page in WordPress. This will make your links look like http://www.your-domain.com/your-link instead of http://www.your-domain.com/?cloaked=your-link
