why not approach other exchanges ? Stocks Exchange it picking up very good! its a bit slow at some time, but its becoming more popular everyday!
Several exchanges have been contacted in the past but we got no reply yet. Right now our focus is to develop the voting features and launching the new website.
After having a functional product, getting listed on other exchanges will be much easier. It will also increase the price a lot so you might struggle a bit with tradesatoshi for now but get it at a good price.
Development is going smooth and we will have updates very soon.
