Have a potential client that runs a summer camp, and needs a secure online registration form for the various camps. I'm not sure if something like EventBrite would work for them, or if there's a better system for that sort of thing. They're a small enough client that the idea of trying to store & transmit this data on their server is going to be out of the question; we'll need an external service for it. - COMPLICATED MR. NOODLE
