Bill: The main page is pretty cluttered with more than one discussion. I propose to make a pretty simple WME, keeping the main page to a brief explanation with an example, and moving the discussions to subpages.
Bob Myers: Makes sense.
For some reason, when I encountered the term han-ko I never associated it with half point ko, but rather a "baby" version (which the term "han" can mean, sort of 'semi") of a "real" ko.
