Hi,
I am currently doing a MA in Globalization, Ethnicity and Culture at the University of Sussex. Though I am not an IDS student, I am very much aware of the reputation and reserach that eminates from the school. Many of the texts that I read for my programme are authored by IDS faculty and indeed the institute is among the, if not the, strongest development focused institutes in the world. I'd highly recommend not only IDS but also Brighton as a great place to live and work! A helpful resource for postgraduate life here in England is www.postgrad.com. Good luck!
