Volunteer-dependency has been a key characteristic for Open source projects. Whether it is through contributing on Github, creating open geographic data on OpenStreetMap, or editing Wikipedia, volunteers are the backbone in many Open initiatives. Consider the following questions: * How might we expand our volunteer recurecruit network and improve the recruitment practices to encourage those who do not typically participate in Open (source) projects? * How do we ensure a diverse, inclusive, and safe volunteer environment/community for those underrepresented within the projects to join? * How do we reduce and resolve volunteer conflicts to maintain volunteer retention? * How do we encourage those who bear high opportunity cost to volunteer for free to still join the initiatives? (E.g. consider a marginalized group in the society whose input and participation could be invaluable to Wikipedia editing... Or a group of refugees who struggle financially but can contribute to the OpenStreetMap on refugee camp mapping...) * Have you worked with volunteers in your Open education/open data/open source/open access projects? What was your strategy of volunteer management and what are areas of improvement you see?
