How do I add a Global Giving donation widget to my organization profile?

On the second page of the organization profile page editing wizard there are fields where you can provide your Global Giving Project ID and Global Giving Organization ID. You can find out what the number is for the project you want to feature by logging into the Global Giving website at http://www.globalgiving.org and visiting your organization or project page. Look for the number in the heading in parentheses, as shown in the screenshots below.
