Yeah, it's difficult isn't it? You want to help by bringing in money, but you don't want to appear like you're there to 'see the spectacle' post-quake (not that I'm saying you are - not at all! But I bet there are people who travel to places after terrible events just to be able to say they went there, for bragging rights).
Amelia, I absolutely love the idea of volunteering post-quake! I would want to do that if I traveled to a country that had recently seen a natural disaster. I wonder how long there will be a presence there helping with rebuilding and such.
