I just heard about something called NY Loves Haiti:

I wanted to let you know about the site, NYlovesHaiti.com, some friends and I launched in response to the tragic events in Haiti.  While we are not medical workers or first responders, we aimed to help make a difference using our skill sets – so we developed the site which lists charities and local events, from hip hop to cocktail parties, being held to benefit Haiti recovery efforts.  We have been floored by the response  and number of people that have attended these events so far and would really appreciate if you would consider posting a short blurb, so that your readers can attend some of these event and perhaps be inspired to hold their own.
