The Community Leadership Summit (CLS), co-located with the All Things Open Conference (ATO), brings together community leaders, organizers and managers and the projects and organizations that are interested in growing and empowering a strong community. Leading minds in community management, relations and online collaboration will discuss, debate and continue to refine the art of building an effective and capable community. CLS will feature moderated and facilitated discussions (unconference), as well as a number of prescheduled stand-alone talks (lightning talks) on multiple community-focused topics vital to the health and ongoing sustainability of open source.
In addition to the CLS, a “Community Track” is organized at ATO since 2016.
From 2009-2018 CSL was colocated with the Open Source Software Conference (OSCON). After a break and an unoffficial Community Managers Gathering at OSCON in 2019 it is now co-located with the All Things Open Conference (ATO) since 2020. From 2010-2013 a complementary Community Leadership Summit West (CLS West) was organized in California at the US west coast.
Main CLS organizer and emcee is Jono Bacon Consulting.
