• A method of managing a gmail inbox such that Inbox Zero is relatively easy to get to, using GTD princples. This is a little outdated and the interface has changed in one or two places, but I was still able to implement it with a bit of looking around in the various settings menus. It doesn't seem to work very well from a phone; I consider this a feature rather than a bug, as it means I'm more likely to do e-mail at my computer.
