Episodic contributors, identified by their infrequent and sometimes unpredictable contributions, are a reality in free/libre and open source software projects. Although episodic contributors can be more complicated to incorporate than habitual contributors, they can benefit a project by introducing new ideas, spreading word about the project, and implementing new features. In this talk I will discuss best practices for managing episodic volunteers, based on a Delphi study of community managers from a range of free/libre/open source software projects.
