I have looked your site and got good impression at first glance.
Here are my suggestions:
1) Could you please add DVC/LTC currency pairs.
2) And also selling or buying is something ambigious.
I mean orders are not so clear, what im selling or what im buying is not easily understandable.
p.s. I didn't register atm but soon most probably ill do.
thank you for your suggestions.
1) Concerning DVC I will have a look.
2) I personally prefer the current way. I am not so happy with ask and bid, since I think it can be even more confusing. I tough the interface is clear enough. It says: "How many BTC you want to spend." and "How many PPC you want to buy."
I believe you had trouble to understand this, since you are not registered. If you are a registered member the interface will be extended buy showing a form to place an order. In the interface design a followed btc-e who have chosen "sell orders" and "buy orders" and I think the meaning should be very clear.
I hope I could explain myself. If not, can you make it more concrete. Maybe only some explanation on the top would be needed.
Thank you again and best
