i'm in australia also.
i've *LOVE* to see this go full on, showing graphs, highs & lows, current prices, etc.
Then the members could create portfolios, and use fake money to buy and sell (like all those eCash and other mods running around - instead we'd give our users 50,000 per 4 months, to see who could create the highest profit at the end. )
this has HUGE potential - much more fun than the arcade 8)
An-net you should really go hard on this - it's a GREAT idea
