This chapter investigates the potential effects of unequal power relations on participation in a group of student teachers and invited professionals in two collaborative workshops in Second Life. The basic research enquiry addresses whether the relative anonymity afforded by virtual world environments has an effect on established power structures, thereby empowering relatively powerless language learners to more active participation than would be the case in more traditional learning set-ups. The data includes recordings, group reflections, and individual questionnaires. Participation was examined from the aspects of floor space, turn length, and utterance functions, and complemented with student reflections. The results show that the differences of floor space and turn length between the invited professionals and the students were small. The invited professionals did more conversational management than the students, while the students performed more supportive speech acts. No major gender differences in participation were found. There was, however, considerable individual variation.
