Is it only me who can't login to MtGox since at least Friday 18 Jun (i.e. a long before hack)? On Saturday 19 Jun I have placed a ticket in the MtGox Support system (#1664) but have not received any answer yet.
It was look like the system accepted my password, but instead showing me my trade page, redirected me to the main page. In a case when I have used wrong password, just to try, system clearly say what password is wrong.
BTW, I have used a special password on MtGox, not used anywhere else :-)
