As the official journal for the International Network for Social Network Analysis, the emphasis of the publication is to reflect the ever-growing and continually expanding community of scholars using network analytic techniques.

From the Editor Welcome to a new issue of Connections. With the aid of a reconstituted editorial board I have identified a number of target areas for articles. As you can see a number of stylistic changes have been made to make the journal more accessible and to enhance its signature. At the same time, all back issues are being scanned and uploaded so that a complete, open access, record of the journal will be available online. All this will improve the visibility of the association and the value of published articles to our members. My target is to produce two issues a year, and to provide a platform for articles that communicate innovation in the use of methodology and novel SNA applications. I am particularly keen on concise and theoretically embedded articles accessible to an interdisciplinary audience. In this issue we launch a section we call Data Exchange Network (DEN) jointly edited by Rich DeJordy and Pacey Foster. DEN solicits articles explaining data collection, aiming to scrutinize research operationalization. This will promote the wider distribution and use of datasets for teaching and research, but also provide examples of good practice in data collection. To thank our reviewers and authors and to facilitate discussion on the goals of the journal, Rebecca Davis organized for us a very well attended reception at the last Sunbelt. We received ideas and feedback on our plans from a good number of former editors and INSNA members. We look forward to a similar event at the Hamburg Sunbelt in 2013. Concluding, I would like to thank Tom Valente, the preceding editor, and the production team led by Kate Coronges, our Managing Editor, for their support and guidance. I look forward to your contributions in developing the journal. Dimitris Dimitris Christopoulos Editor, Connections dimitriscc.wordpress.com
