The volume is quite low. Perhaps, and this is only a suggestion, start off without charging any fees, once you have a larger customerbase that would be the time to introduce fees.
Britcoin has been completely transparent with this in that it is waiting for accreditation or something before it can charge customers, and now the volume is high.
Of course, the low volume may be due only to the fact that the exchange is incredibly young, of course.
While we do charge a small commission to pay for server space, bandwidth, programmers, designers, and other costs, this division of the company is not profitable.
The reason for imposing such a commission is that we don't have the level of investors that Britcoin has to pay such costs.
We like to pride ourselves on transparency, be upfront with commission, code and who we are as a company.
We are a young exchange and yes your correct the volume is currently low, the exchange is increasing in activity daily, with a little over 40 users in three day's now and growing, as Australians become more aware of Bitcoin, we have forecasted for the exchange's volume increase within the next 3-6months.
We have had some positive feedback from users please goto the following link https://bitcointalk.org/index.php?topic=37079.msg462831#msg462831
