To add a widget to your homepage (or your profile page -- it works the same way), click the 'Add A Widget' button that is underneath your profile picture on your homepage.
You'll get to the 'Widget Directory' which is a list of all of the widgets that CafeMom has right now (we'll be adding lots more). Pick the category that you are interested in, and then look through the different ones available in that category. Choose the one you want and click the 'Learn More' button.
