In this essay we seek to both discuss and exemplify the transformation from collaborative work and dialogue to collective thinking and action. We offer a manifesto for building feminist coalitions at a historic moment when these appear to face growing obstacles. We argue that it remains as urgent as ever for those who are in a position to do so to forge networks and to build spaces for action. Ultimately, we call for the political potential of polyvocal and polyamorous collaborations that reach across disciplines, time zones, and borders and that take the flexible and creative shape of gatherings.
