There are way too many steps in using MPC. To have to explain to patients that they need to copy the token and then paste it into a new message rather than forwarding it seems counter intuitive. The instruction PDF is several pages long. We need to be able to hand out or display a single A4 page that clearly explains the steps required to send the e-script to their pharmacy. If you don't get the communication side of it right then you may as well forget it.
