Added 2 MEW addresses and they both complain about failing to fetch decimals for an ether address that is not mine - not working at all

Thanks for the report. I've looked into this issue and have found and fixed the root cause.

When a new Ethereum token is added to our site, we also need to fetch the number of decimals the token has. Since Etherscan.io doesn't expose such an API, we had to fetch the decimals through another method – and this method had temporarily stopped working.

We've fixed this, and your Ethereum addresses should now be working. We've also set up a notification to notify us the next time this occurs. If you're still unable to get your Ethereum addresses to work, please let us know!
