Yup you can trade them like normal shares, but with a bit more leverage up until expiry at that point you either sell them on market, they expire worthless, or you convert them into shares, which will be good if they hit REE's and we run past the teens and your option allows you to convert them paying 0.005 per DMN share :)
March 2013 expiry nice and long dated, these options have the potential to beat the main share price once we start moving past 0.005 on the heads due to the very low time decay component.
