Google have a nice little web-app called Google Notebook. Just a handy way to make notes to self, which can be accessed anywhere you have Internet access. It used to be available at http://notebook.google.com. For reasons utterly beyond me, that address no longer resolves at all; you must use http://google.com/notebook. Highly irritating; I thought that they were meant to be good at user interfaces?
(Edited: original said 'make notes to elf'. I doubt I'd want to do that; I can't even speak Tolkein's make-up languages.)
