It's been mentioned on the wiki page at
http://www.prowiki.org/wiki4d/wiki.cgi?WindowsAPI, but I think you're right that
it's not in the "Translation instructions" section (and it probably should be there).

I get the feeling that the WindowsAPI page at Wiki4D has gotten way too big to be
efficient. I think that it should probably be split into subpages, but I would be
afraid of stepping on the toes of the WindowsAPI team by doing it myself.

(Also, I wonder if it would work better to store the content that's current at
Wiki4D in the bindings wiki instead [http://www.dsource.org/projects/bindings],
since it is part of the bindings project and dsource wikis have a cool way of
formatting D source code.)

Actually by my count, it's already been mentioned twice by other people in the
Bindings forum.

(The bindings project doesn't really have formal leadership, though, so I'm not
sure who's reading that forum anyway.)
