quick question: how do I transfer goxBTC to another gox Account? Can't find that option, and I am verfied.
it's easier on cryptsy, they have a transfer button

Its simple, Put a gox deposit address in the withdrawl field.
wow, would expect that to hit the blockchain and not be "off-blockchain"
That is silly. Any good exchange would be keeping as much OFF the chain as possible, so as to not spam. If it's an internal address, and there is a large hotwallet, then all the system needs to know is that the addresses are gox's and then update the relevant accounts. This seems beyond obvious.
