You'll notice that you now have the option to prepare and save draft emails, hurray!
Don't forget to save a draft (it won't automatically save for you) if you want to come back and complete a message at a later date.
Some of you will have noticed that if you are preparing an email for say, over an hour, that your computer may log you out of MSF (for your own security) and your message is lost. Having a draft option (and saving it every half hour or so) will put an end to losing such poetry!
