Damien,

As far as available BTC/USD, we will roll back in accordance with Gox, as we use their history. This is likely to be a big mess. I'm going to turn off Mt. Gox facilities on bitoption until things settle down; you will still be able to trade, but you won't be able to send / withdraw until I'm sure we're settled properly.

Personally I had a bunch of buys down at $7 or $8 on Gox; looks like I wasn't aggressive enough!
