"WYSIWYG" is a well-known "computerese" acronym for "What You See Is What You Get." It became generally well-known in the late 1980s as a description of the Macintosh user interface (which the Windows interface would more-or-less duplicate later), especially in regard to "desktop publishing."
If Susan means anything ELSE by "WYSIWYG," I trust they she'll enlighten us. Or maybe she'll explain why she chose this name and how she feels that it is appropriate as her identity.
