As the "megajournal" has become more familiar as a concept, the term itself has come to feel more nebulous and limiting. Digital technology has enabled a shift both in the scope of published research and also in who can access it. But publishing is not just about the technology, it is foremost about the academic communities it supports. Jason Hoyt reflects on the evolution of the megajournal and, as PeerJ turns five, announces a change to its editorial model that will incorporate the power of communities into the megajournal format. PeerJ will introduce section editors to take community leadership roles, working with existing academic editors to create greater consensus in publishing decisions and helping to curate and highlight important new research findings. Also, to celebrate this fifth anniversary, PeerJ and PeerJ Computer Science will waive the article processing charge (APC) for all manuscripts submitted in February.
