C2w is a good site but contest are limited and so the winners all there is a system for redemption of credit to be won but they dont send the prize to every one but still winning the heart of million indian and very successfull in china too they are also giving genuine prizes and very much ahead of their competiters like indiatimes or rediff in competition it takes surfurs very speadly to home page when they come to an end to contests. one can know about its credit situation currently and winner updates are there too.
i think it will be a great success.
