If like many folks you are confused how to get the forked coins from upcoming forks such as Ethereum Classic and the new Callisto Coin, then you are one of many.
This is where exchanges come in. While most exchanges are not know for their trustworthiness there are a few standouts, and ones that support certain forks. I dont recommend keeping your tokens or coins on Exchanges for any long term holdings, due to potential of risk associated with Centralized exchanges.
With that being said however, the easiest and fastest way to get those forked coins is via an exchange such as HitBTC for this fork in Ethereum classic.
They announced in a Blog post their official support for this fork which will work for anyone owning the coins at the time of the snapshot.
Watch the countdown timer here. And get your coins on HitBTC to be sure you'll you receive them.
