An issue with chat is that it is often difficult to archive a chat and extract important information from it after it has been closed. To overcome this problem, we allow people to save their chats and store them within the in-box, giving them the same abilities to search and organize them as regular email. In addition, a chat may be started from a thread and saved as part of it.

An innovation that we introduced with the Remail chat component is the sign-off message. When a user closes a chat window, a message is inserted into the other participant's conversation stream, indicating that the chat partner has left the session. This indication reduces any confusion regarding whether or not a chat has come to completion.
