Getting Things Done Wiki

Description
This wiki is dedicated to GettingThingsDone, a book by DavidAllen whose apt subtitle is “The Art of Stress-Free Productivity.” You’ve probably heard about it around the Global Interweb or have been buttonholed by somebody in your office who swears by GTD.

It is a customized version of TiddlyWiki, written in HTML, CSS and JavaScript to run on any modern browser without needing any ServerSide logic.

Then it was a FlexiWiki and later on he changed the engine to ScrewTurn Wiki.
