I got my HDG token around 1+ day ago.
ok, when i check my MEW it doesn't show up at all. anything extra we have to do for it to show up?
You can check thru etherscan.io with your address under "Token Transfers".
This will be the address sending to you; 0x13a8b6434bd5cef0924814f7414482529b51df2a.
Or you can check thru ethplorer.io.
Edit:
From that address, it (that particular ERC20 token) shows contract address as 0xffe8196bc259e8dedc544d935786aa4709ec3e64, with 18 decimals.
You may now custom add that contract address, the 18 decimals, and the symbol HDG in your MEW setting to load the token.
