In order to find the token site, and whitepaper, you have to scroll to the bottom of the web app, and click on "about Bancor", This will take you to the informational site.
I have tested the system and it works very well for me, compared to anything else that I have evaluated. The trading site was very easy to use, and works well with the metamask wallet. Currently supports about 60 "smart tokens" which is rapidly increasing. No exchange fees. Only cost is for etherium gas.Good user interface and trading experience.
