Rise has a website just around the corner, if not today then most likely Monday or Tuesday. Reasons for the delay is there is a user login and tracking function that the developers are finishing off.
There is a white paper that is going to detail security and ease of use functionality, it's on it's way once testnet is up.
After speaking with Justin, the lead developer, his priority after fixing a firewall problem (that was preventing provisioning / configuration on the server for a release of testnet yesterday)... was that he was 90% ready in terms of being able to make it public. I would expect it to be released very soon.
