By this time the developers should have already launch a beta site for us to view how the exchange marketplace should look like. We need to have a first hand experience on thier platform. We can also give some feedbacks that will help them for the additional development of thier platform.
I think they are on schedule with the timeline of their project. Beta development i think you can find them on the road map. I agree with you that it is better for us to experience how their platform will work and for us to give feedbacks for them to improve if there is any.
Actually we experience it already but we all needs to categorize what is going on to do for us to develop the project in appropriate way by standard form. The platform is good for everybody not just for the project but as well to the person involved in the project. It means their is a directions that needs to follow.
