Due to tragedy the Haitians are facing, many groups around the world are helping in different ways, from collecting goods, supplies and monetary donations. Be careful of responding to scams. If you are not sure what to do, stick with legit organizations like the following:
Islamic Society of North America
World neighbors wn.org
There are other organizations helping, but the above is to give you an idea and a place to start. I am not being compensated by any of these organizations to list them. I just want to offer some legit resources.
