Delhi in February.

Hi there, 

I wondered if anyone else was taking part in the Language and Culture week in Delhi in February 2012? 

Also, if anyone has previously traveled to India, do they have any tips? Anything would be much appreciated, no matter how silly they may sound! Any ideas or suggestions on things like keeping healthy,places to eat, places to visit and not to visit, things you may seriously need that you can't get in India, etc etc. I've never been to India before so all suggestions are welcome. Thanks.
