|This exploratory article describes and develops theoretical notions of how coordination takes place within mobile network societies, that is, societies where travel, ties at-a-distance, email and mobile communications are widespread. The article brings together studies of travel, communications and social networks through a particular focus upon the multiple processes of coordination. We specifically examine how communications are used to coordinate meetings between friends and family members, and how these 'coordination technologies' have in part changed the nature of arrangements to meet and conduct face-to-face meetings. We show striking changes in technologies and cultures of coordination - a shift from punctuality effected through clock time to a flexible and perpetual coordination effected through email and mobiles. This empirical research addresses specifically located embodied practices of coordinating meetings and it illustrates how coordination is a practical, relational accomplishment and how coordination cultures are variable amongst young adults.
