Which is better, using the Plugin or manually installing Woopra?
The Woopra WordPress Plugin is designed to work with WordPress self-hosted, single version installations. It has built-in features to allow you to customize Woopra from within the WordPress Administration Panels. You can add similar customization within the Woopra JavaScript. See the Woopra Developers page for more information and details. Check out the Woopra API for information on creating more custom features for various website and blog platforms and third-party applications.
