You can save the contents of a compose window at any time before or after it is sent. If you save it before sending, the file that you save it in will be updated when you send it so that it contains the final version. If you do not save it before closing the window or quitting the program, InterNews will ask you if you want to save it. After sending, InterNews will ask you if you want to save it. You can use this feature to keep a simple log of sent articles and mail messages by saving them all in a folder. There are some composing preferences that can be set to modify this behavior.
