I'm starting to wonder if Sony should just turn Pottermore over to Zynga (oh horrors!) Seriously, each Zynga game has millions of users, while there are as of today only 666,703 registered users of Pottermore. Yet it's Pottermore having these server issues.
Very frustrating, but it's too much fun pretending I'm a student at Hogwarts to give up on Pottermore.
