At the beginning of this month, we had Joshua Porter in the office to present his Design for Sign-up talk. Designing for sign-up should be simple, yet it's often the most challenging area of your design. Josh had some great ideas on how to increase the ease of sign-up and how to motivate your users to want to.We got back together with Josh to follow-up on the seminar so we could answer a number of viewer's questions that we didn't have time for in the seminar.
