Good point about where to keep the list. If the house burns, you don't want to lose the list as well.

When i was doing my Masters, i would e-mail myself my thesis once a week (or more often if i was writing a lot) so i would be able to access it from wherever if something happened to my computer, memory devices or whatever. As long as you remember where it is kept (what e-mail address, what folder), cyber space is always a good option.
