I have looked at that site about a month ago, found it by just wondering around the net, I am not to sure about it myself. The format of trading ounces and grams of gold instead of money may lead to some misunderstandings.
Also the design of the site was less than impressive and going with my golden rule (bun intended) 'If they do not take the time to design a good site what does that say about the company'. Ofcourse that was a month ago and they could have total redesigned the site. I should go and check it out before writing comments like this but that means deleting and rewriting and since I already have this written....
