It's not just the efforts of celebrities that have made a difference in the lives of hurricane victims. The efforts of viewers like you have been instrumental, from donations to shopping on the Oprah Katrina Homes Registry.
To date, more than $11 million has been donated to the Katrina project.
The original mission was to build more than 100 homes in the Gulf States, and the construction continues. More homes are being built in Jackson, Mississippi, and a second street of homes funded by NBA player Kevin Garnett was finished in August. Now, 18 families have started new lives there.
"You all saw where your money is going," Oprah says. "Thank you so much."
