This paper introduces a test sign-up application developed for a math department at a university. The requirements, design, and final software product are presented, along with one very important unexpected problem that arose after completion of the work--the system to be implemented and maintained by the client was not compatible with the platform supported by the client. In spite of the ensuing frustration and challenges, the end result was a success in many ways. In addition, it was a great educational experience for both the students and faculty involved in this project.
