Trade dollars replaced by bitcoin?

[thesilverstarman]

There are many trade exchanges around, eg Tradebart here is Australia. Great idea, but they take fees in cash every month, and its hard to spend your accumulated trade dollars, which have an expiry date. Bitcoin would be a great alternative. All we need is someone to make a business trade exchange based on bitcoin. Any takers?

What's a trade exchange, exactly? What do you mean?
