This paper introduces the concept of editable chat logs for shared workspace systems. In shared workspaces offering a chat for synchronous communication, editable chat logs allow to keep and archive transcripts of chat conversations as documents in the group memory. As any other document in the shared workspace, the transcript can be subject to future conversations. Moreover, the transcript can be edited to create new documents or to reuse (parts of) the conversation within other documents. In this way, editable chat logs provide for a seamless integration of chat conversations and documents.
