This article studies the formats Do we X, Should/Shall we X, and Let’s X in order to deepen our understanding of face-to-face collaborative interactions at the computer. We use 6 hours of data of university students collaborating in British and American English, and our methodology is Conversation Analysis. We demonstrate that the participants display and orient to the immediacy/remoteness of the task, as well as their entitlement to carry out the proposed task, when they put forward a proposed action. To (...) do so, they use specific formats, specific verbs, and display specific tasks depending on their needs, emerging from the unfolding of the collaboration. We argue that collaboration is not only a matter of organising the accomplishment of a set of tasks, but also of displaying what kind of task is being proposed, and to what extent the speaker is entitled to the proposed task.
