Did you notice Vitalik linked to steemit at the end his blog post:

>You may use the Ethereum Classic Explorer here to verify that ETC balances have been transferred. A more detailed community-provided guide can be found here

"The community guide" is this post from Hive account@pauls : https://steemit.com/ethereum/@pauls/ethereum-fork-step-by-step-guide-to-safely-splitting-your-eth-etc
Nice work Hive account@pauls
