Building a Strong Community Culture presented by DC407

Two organizers from DC407, the DEF CON group in Orlando, open with the problem of turning passive attendees into active members. Their meetings are free and built around a talk or workshop, with socials, a sticker swap and a book swap. Students and mentors often send newcomers their way, but new people can feel like outsiders in an established crowd. The group answers this by greeting newcomers, introducing them to a few friendly members, and stating openly that the group is welcoming, with attention to microaggressions and a code of conduct that addresses harassment. Organizers suggested adapting that code to each venue's rules.

The middle of the talk covers growth. DC407 plans speaker slots two to three months ahead, sends written confirmations, runs a Discord with speaker roles, and offers short lightning talks on any subject so first-time presenters can start small. Members are encouraged to help set up events, volunteer with other local groups and B-Sides, and build a network of advisors so leaders do not carry everything alone. Consistency matters: a regular monthly cadence, steady online presence and word of mouth build the group slowly, even when few people show up.

The speakers also shared practical numbers. RSVPs typically convert to 40 to 60 percent actual attendance, a lesson they learned after overbuying pizza. They closed by describing the organizer's role as a facilitator who looks after a community that belongs to its members.
