I did get the 3,000 I bought showing in my Ethereum wallet as ERC-20 tokens.
Really? What (if anything) did you have to do to see them? When I look at my wallet on Ethplorer, it's not there. When I enter the contract information on MyEtherWallet, it shows a 0 balance. But, maybe I'm doing something wrong...
Share your process?
I just checked 3 different block explorers and it shows on all 3:
etherchain.org - Shows on main page on left hand side under "Top token balances" for which you can also click on "View all" to show the complete list.
ethplorer.io - Shows on main page on the right hand side under "Token Balances".
etherscan.io - Click on the "View tokens" pull-down from the main page to see it.
