Does anyone know if there is an official GTD wiki representing the collective knowledge of those in this forum?

I also use the word "knowledge base" cuz I'm not referring to TiddlyWiki which I see many references to here.

One search on Google resulted in this one:

http://wiki.jeffsandquist.com/defaul.../HomePage.html

Want to know if there are others out there - especially ones that are focused on extracting knowledge out of this forum.

Any pointers appreciated!
