yea this video is freakin awesome. You know how many times I have started a project and need and api or a website where people can either sign up on the website or on in my case one of my iphone apps. It would awesome to see added to this. A web UI from this app. So how to add a front end to this app where users can sign up and then also I could send a request from my ios app sign up page to this service and it will create a user for me and give me token so I can call the apis'. That would be so rad
