7 From the Editors This volume represents the proceedings of ECSCW 99, the 6th European Conference on Computer Supported Cooperative Work. The conference marks the 10 years anniversary of ECSCW, an international forum for research activities from various technical and social disciplines. The conference alternates with the ACM international conference on CSCW to provide annually a principal point of focus for CSCW research. The program of technical papers presented here is the result of a difficult review process. This year the conference received 94 submissions of very high quality from which the 23 papers making up the technical programme were selected. Both the number of submissions and the quality and diversity of the programme presented here are testimony to the health of the CSCW community. We are sure that you will enjoy the papers in this volume. The technical papers in this volume are only one aspect of a diverse and dynamic event such as ECSCW. The technical paper program is complemented by tutorials, workshops, demonstrations and posters reflecting some of the most exciting and novel aspects of CSCW. These activities are essential to the success of the conference and the continued growth of the community. This conference could not have taken place without considerable enthusiasm, support and encouragement as well as sheer hard work. Many people have earned the thanks of those who attended and organized ECSCW 99. In particular, we would like to gratefully thank: All those who submitted to the conference. The standard was very high and reflects well on the research work in the community. All of those who contributed to the conference through workshops, tutorials, posters, demos, and paper presentations. All of those who contributed to the organization of the conference. Planning a major international conference is a complex endeavor and many people made significant contributions to realizing a successful conference. The Student Volunteers who work so tirelessly during the conference to ensure things run smoothly. Those members of the Conference and Program Committees who gave so freely of their time and energy to ensure that the conference was both smoothly run and of high technical quality. The many individuals we owe our thanks to are listed elsewhere in this volume. The many sponsors and supporters of ECSCW 99 for their contributions to the conference and to the CSCW community generally. Many of these people have been involved with the ECSCW conferences since the first conference 10 years ago.

8 X We would also like to acknowledge the organizers of the ACM CSCW conference for the support and encouragement they extend to this conference. The close cooperation between ECSCW and the ACM CSCW conferences allows us to continue the growth of a truly international research community tackling the problems core to CSCW. Between both conferences we have been able to establish an annual international conference on CSCW for the last decade charting the development and maturity of the discipline. These proceedings represent the start of the next decade of international CSCW research and the further development of our research community. The future appears to hold considerable promise for us all. Susanne Bødker, Morten Kyng, and Kjeld Schmidt
