This talk is targeted at anyone involved in an open source project who wants to find more contributors.

Programs like Google Summer of Code often provide excited students who disappear after a summer's work. Meanwhile, request for help emails on development lists are typically met with silence. Hackathons create a flurry of commits, but then we never hear from the participants again. Expanding your team is possible, and it requires care in terms of outreach, expectation management, and mentorship.

We will discuss three major forms of outreach:

• One-on-one check-ins with participants,
• Periodic drives to bring in new contributors, and
• In-person teaching events.

Each one has "do"s and "don't"s associated with it. This talk digests the experience of effective outreach into practical strategies that you can re-use within your project.
