This article presents a study of the discourse characteristics of interaction within a virtual community. The data are from the text-based chat forum of an online community of learners and teachers of English. The forum is the meeting place for community members, and is an international site of language use with participants from a range of linguistic backgrounds. Within this context, some pertinent themes are investigated which relate to a relatively recent form of discourse, synchronous text-based computer-mediated communication. The discussion (...) centres on the interplay between the technological attributes of the medium and the linguistic, discourse and sociocultural conditions within which the participants interact. How do these elements combine to shape the discourse? This question is addressed with reference to the cohesive feature of conversational floor. Because there is a lack of coordination of turn transfer in SCMC interaction, conversational floor emerges as an organizing principle in preference to models of conversation based on turn taking.

This study describes discourse features of messages posted to an Internet discussion forum about depression based on the analysis of a small corpus of message texts. The message texts were classified into three types: problem messages, advice messages and thanks messages, and salient discourse features of each message type were described and analyzed in terms of discourse function. Features of problem messages included: frequent use of metaphorical language to describe symptoms, use of or type questions to request advice, and a (...) general lack of direct requests for advice. Advice messages were characterized by casual style and exhibited a variety of discourse patterns with the common function of expressing positive regard and solidarity. The occurrence of these patterns can be related to the special interpersonal needs associated with the discourse function of giving advice. Thanks messages were responses to advice messages, and usually included some expression of thanks for advice, but interestingly, thanks message writers never indicated that they had acted upon or would act upon the advice they received.
