Sorry to hear that and not to be insensitive - but I think that number is probably a rounding-error to a good chunk of traders out there! Imagine all those who had margin accounts and got wiped!
I know, you're not being insensitive. :) I'm not making a fuss about it though, it was a part of the risk anyways and it was an experiment in the spot market. I built that 1200$ out of 200$ of initiation cash, so there actually is little to no damage anyways. But you bring a valid and disturbing point, there are a lot of folks out there now that lost tons of money and got margin called - most of them probably over leveraged, not a pretty sight.
