Expatriate Forums in India

I'm a 23 year old American moving to Delhi to work for a philanthropic foundation and am looking for a roommate or two to live with. From what I understand, South Delhi is the best option. I'm fairly easygoing and would prefer people that are social and like to travel and go out. My budget would be around Rs.15k and I would prefer to live with people with international experience. I've been through Africa, Europe, and Asia and am very comfortable in new surroundings.
