Based on longitudinal data from a three year ethnographic study, this article uses discourse analytic methods to explore the literacy and social practices of three adolescent English language learners writing in an online fan fiction community. Theoretical constructs within globalization and literacy studies are used to describe the influences of new media and technologies on modern configurations of imagination, identity, communication, and writing. Findings suggest that through their participation in online fan-related activities, these three youth are using language and other representational resources to enact cosmopolitan identities, make transnational social connections, and experiment with new genres and formats for composing.
