ShapeShift has built a tool for users to easily separate their ETH and ETC. This is important since the fork happened - many Ethereum addresses have both Ethereum and Ethereum Classic balances, and sending can inadvertently result in lost funds on one or the other chain. Anyone can use the ShapeShift Ethereum Splitter to "clean" their balances, so that their Ethereum goes to a clean Ethereum address, and their Ethereum Classic goes to a clean Classic address. Funds can be sent into the splitter from any wallet or exchange.
