About the project

The OpenSuspect project is a team endevour of many volunteers. Our members work on the project in their spare time, often after work or school, so we don't have a rushed development schedule. Many of us regard the project as valuable experience in not just software development but also in team work. Our most important goals during development: * Supportive community * Openness * Keeping extensibiliy in mind * Focus on learning

However, we also understand that a game needs a direction, and some problems are easiest to solve in a top-down fashion. Therefore, we agreed to implement a team structure, where each team have their responsibilities, and are organized by an elected team leader. The project is guided by the council containing the team leaders and a few elected project coordinators, who set the goals together. For the current teams and leadership, check the CONTRIBUTORS file.
