Draft of personal message

Hello everyone,
I am not real tech saavy hence the question. When typing a personal message I sometimes hit a button that leaves the page. I was told that a draft is saved like in emails but I can't seem to find where they are listed so I can retrieve it and finish. As of now I am just retyping everything. Sure would help someone who is all thumbs sometimes.

Thanks in advance for your help.

Don't hit that button. There is no provision for drafts like an email.
Type out your PM and send it all at one shot.
