I think everyone should do whatever they can that is within their means to help the survivors of Katrina. There are a number of charities (especially the Red Cross) that you can make donations too.
I am a Methodist and am donating through our church's organization. You don't have to be a Methodist to donate (of course) so if you want to make sure your donations go to this very cause you can donate to The United Methodist Committee on Relief's (UMCOR).
You can make your donation online at:

The site also tells you what you can do to make "food buckets" for relief (which is something every one can do(.
