From Jessica (@jessicalawrence) at NYTM (NY Tech Meetup) re the response to Sandy:

NY Tech Meetup and New Work City are organizing volunteers with technology skills to help with relief efforts and help New York-area businesses and organizations get their technology back up and running after Hurricane Sandy. For now, we are starting with creating a database so that we have a group of people who have already raised their hands and are ready to go as it becomes more evident which organizations and businesses in the city need help.

If you have skills to offer, please sign up here: http://bit.ly/hurricanetechvolunteers
