To me it looks like MTGOX all over again, first there were excuses about the trading volume which everyone believed in, and then one morning there was Mark saying he's sorry.
they now have over 10,000 more users online than when the problems started and i presume it takes weeks or months to get more staff and upgrade servers. they should either restrict users online or new signups until they've got their shit together.
i still think it's a genuine capacity problem. still, no one should be leaving coins on there.
