Freaking crap. I can't log into any of my accounts at MyBitcoin. I thought I had been hacked at first. But then I made a new account just to be sure. And I couldn't log in with that either. So they are preventing logins, yet the the message is saying invalid password/username. I'm a little bit less worried now, as they could just be doing some sort of of upgrade. Lets just hope it's not something much worse. Most of my coins are in MyBitcoin.
