This paper analyses the online talk of students working in groups collaboratively in a hybrid university course. In particular, this study investigates how students situate themselves relationally through their use of language and how particular moments of talk contribute to the construction of community in an online classroom environment. The data suggest a strong sense of community across groups of learners, with student-student encouragement and peer acceptance emerging as the most salient themes. These findings are considered theoretically in relation to contemporary literature on accounts, facework, politeness and apologies. Practical issues and research avenues tied to classroom format and computer-mediated student culture are also discussed.
