Having Mozilla Thunderbird save a message as a draft ever so often in the background and while you are composing it is a great way to watch your computer inspire you with semi-autonomous action.

- Go to the Composing category.
- Select the General tab.
- Make sure Auto save every __ minutes is checked.
- Enter the desired frequency for saving (three minutes is usually reasonable).
- Close the preferences window.
