I've tried some features of the testnet, I like the fact that the product is actually working, not so common. However, I think UX should be improved a bit. For example, the projects information is a bit hard to read and I don't understand when I'm executing each role. When is the mainnet launch?
We're working hard on improving the UX of the testnet. At the moment, we're working on several implimentations that we received from the feedback on the testnet, you can read it
here.
We're planning on launching the CGS to mainnet in September.
