DZ has an online alumnae chapter called Surfing Sisters, and I just learned today that the exec board has made a $500 donation to the Red Cross earmarked for Katrina relief.
We're waiting to find out what our national HQ is going to do. Right now, we've been advised to give directly to reputable charities that are set up to help hurricane victims. (Usually, we would make donations through our DZ Foundation and they would total everything up and send it to a charity. However, because it takes a while to send things through Foundation and have it go out again, our HQ has instructed us to just give directly to the charities themselves so that people get the aid more quickly.)
