Marketing the event on social media
Every event is preceded by announcing it in FOSS United forum and social media with talk posters, schedule and agenda. While posters aren't essential, sharing event details on social media—with or without them—is important as it helps to spread the word about open-source and about the organisation.
While preparing posters, stick with the standard FOSS United templates, color schemes and fonts. You can also refer to the template created by FOSS United Chennai team here for reference.
