Chat communication has been investigated within the frames of 5thD (Fifth Dimension). The study is based in field-material from two chat sessions, between children in Ronneby-Barcelona and Ronneby-Denver. During the chats there was plenty of interaction between children and, assistants, which is illustrated with the help of patterns of communication. The analysis of the data shows that chat is more than an interaction between two persons, it even connects two social settings. The thesis also deals with the question of how to create meaningful chat, since this did not occur in an entirely satisfactory way during the above-mentioned chats.
