Hi,
Been aware of bitcoin for about a year now, but only recently taken it seriously.
Made a few trades recently and wiped out nearly half my first $500 deposit into MtGox with the madness over the past couple days.
Logged in today to find my entire account wiped out, similar to this

I have a support ticket in for this issue, but just a warning to newbies. Probably not a good idea to keep too much in the exchange. Hopefully it will be resolved.
