摘要：This article presents an investigation of the organization and structures of talk-ininteraction
over work distant meetings. The analysis is based upon naturally occurring interactions
consisting on a corpus of video recorded webconferences in a company. Focusing on a collection of
openings, I aim to describe how participants take into account the sociotechnical context in the
accomplishment of their actions. I show how specific sequences of talk reconfigure meeting openings.
