I found the Signedness (http://wiki.bennugd.org/index.php?title=Signedness) article by searching with the word "unsigned" but i think it could be made easier to find if included in a category like General (http://wiki.bennugd.org/index.php?title=General) or Language (http://wiki.bennugd.org/index.php?title=Language)
Are there any other programming features that are not in "General" or "Language"
