GTD (Getting Things Done) TiddlyWiki

GTD Tiddly Wiki is a GettingThingsDone adaptation by NathanBowers of JeremyRuston’s Open Source TiddlyWiki. The purpose of GTD Tiddly Wiki is to give users a single repository for their GTD lists and support materials so they can create/edit lists, and then print directly to 3×5 cards for use with the HipsterPDA.
