We are particularly interested in the strategies and processes by which new people join the existing community of software developers, and how they initially contribute code. Analyzing data from multiple sources on the Freenet software development process, we generate the constructs of "joining script", We are grateful to helpful comments from two anonymous reviewers. We also thank Chris Argyris, John Seely Brown, Eric von Hippel, Stefan Haefliger, Petra Kugler, Heike Bruch, Simon Gchter, Simon Peck, and Hari Tsoukas for helpful comments and suggestions. Ben Ho and Craig Lebowitz provided technical assistance with data importation and parsing. We would like to thank Ian Clarke and the Freenet developers for their willingness to participate in our study and providing key insights into the open source development process. Karim R. Lakhani would like to acknowledge the generous support of The Boston Consulting Group and Canada's Social Science and Humanities Research Council doctoral fellowship.
