By far one of the most organized aid efforts post-Sandy:

Occupy Sandy is a coordinated relief effort to help distribute resources & volunteers to help neighborhoods and people affected by Hurricane Sandy. We are a coalition of people & organizations who are dedicated to implementing aid and establishing hubs for neighborhood resource distribution. Members of this coalition are from Occupy Wall Street, 350.org, recovers.org and interoccupy.net.

Occupy Sandy is where it’s AT!
