Things you can do to help those affected by Katrina:

1. Donate money to the Red Cross

2. Donate your time to entering data about missing and found people on the Katrina PeopleFinder Project.

All you have to do is log in, select unclaimed data from the set of sources specified under "Ready for Claiming" and then enter the data into the New Orleans Network Site. The instructions are clearly stated, and your efforts will help create a centralized database that people can access to search for missing and found people.
