Widgets are cool extra features-things like weather forecasts, stock quotes, archives of your articles, and even videos from YouTube-that add fun and functionality to your site. You can use one or several or none at all. Each one does something different.
To add one, just select the Widgets tool. Click on a widget on the left to see a preview of it on the right. Most widgets come with various options, which you'll also see on the right. Just make your choices and click "Add Widget" to save your changes and close the window.
You will now see your widget in your broadcast.
