This is an official call for sessions for a "Community development and Marketing" devroom, hosted at FOSDEM 2013 on Saturday, February 2nd. In this devroom, developers with different profiles and backgrounds are invited to brainstorm about aspects related to software projects which are beyond the code itself, but nevertheless crucial for keeping the project alive, such as marketing strategies useful for attracting users and contributors, processes for managing the dynamics of the community, and open source solutions for project lifecycle management. While Marketing and FLOSS have long been considered incompatible concepts, recent history has shown that marketing strategies properly tailored for the FLOSS world can be of real help for open source projects without tainting their ideology. Good marketing can be an essential instrument for reaching out and expanding the community of users and contributors. You are invited to showcase best practices and successful collaborations between marketers and developers, to discuss marketing in a typical hacker environment, and to participate in establishing a link between communities and in creating opportunities for collaboration. Furthermore, you are invited to exchange ideas about what works for keeping a community in shape: how to encourage contributions from new members, how to keep people motivated, how to work across time zones and cultures, how to handle conflicts, what are the processes for naming new committers or for accepting patches. Presenters can talk about their favorite combination of tools for version control, code review, continuous integration, issue tracking, documentation, as well as full infrastructure setup scenarios. It will be a great environment for learning from individual success stories about new ways of working better inside an open source community.
