Google has released iGoogle Themes for Causes in partnership with non-profit organizations for you to show your support for the cause that inspires you most by adding that theme to your iGoogle page. The intent of these themes is to raise awareness as well as donations. Each theme has a "Donate" link that appears in the upper right-hand corner to make your holiday donations easier. We also encourage you to share your favorite Theme for a Cause with your family and friends.
