What can you change in cloudbill? It sounds like you're saying you can change credit card information which I'm unsure how but it sounds like you can update your address, passwords, and everything else it seems like. How are you guys able to do this as I believe backend systems like Yoodle doesn't allow this right? Currently does the system support all kinds of banks and bill payments already?
