Chatlink sessions worked differently from chat rooms, and they were a lot more expensive to host. When you opened a chatlink, an insubstantial copy of your avatar was projected into another OASIS location. Your avatar wasn’t actually there, and so it appeared to other avatars as a slightly transparent apparition. But you could still interact with the environment in a limited way—walking through doors, sitting in chairs, and so forth. Chatlinks were primarily used for business purposes, when a company wanted to host a meeting in a specific OASIS location without spending the time and money to transport everyone’s avatars to it. This was the first time I’d ever used one.
