I understand it's possible to list items for sale, with a BTC price pegged to the USD.I realise that most people using the site are American but there seem to be healthy amount of English people on here to justify pegging prices in GBP - and certainly the Euro would be worth looking into as it's more widely used and has more purchasing power than the dollar. (Although admittedly the dollar is a more popular reserve currency).I assume SR uses MtGox rates to work out the spot rate?V.
