Given the number of requests to get aid to Haiti, both healing energy and monetary, I would like to mention that I feel that the best way to get money and supplies to victims is to do it though the Red Cross.
I have personally dealt with the Red Cross during one of my own emergencies.
The Red Cross actually had fifteen people in Haiti when the disaster happened (they were doing shot clinics), so they had eyes on the ground to help the incoming voluteers get oriented. The Red Cross is also used to dealing with government red tape, and corrupt political systems; they actually know ways to make sure the aid gets to the victims while avoiding lining the pockets of corrupt politicans.
You can learn more about the Red Cross though the Red Cross website.
