The popularity of the guide is gratifying -- it gets several thousand hits every day -- but that very popularity makes it impossible for me to answer random questions and settle office arguments.
So I regret that I can't give personal responses to most such queries sent my way. Besides, I'm not an authority to settle such debates. You can get a wider range of responses from the newsgroup alt.usage.english, or you can check out the Additional Reading section, or you can browse some of the links to other writing sites.
If, however, anything in the guide is unclear, inaccurate, misleading, or simply missing, please do drop me a line at jlynch@andromeda.rutgers.edu.
