Miniluv, they're silent on the point! The pronouns section does give examples in which "who" is used to refer to people, and I can't find any examples that use "that" to refer to people, but I can't find an explicit direction. That's why we call on S&W to a lesser degree than Chicago: it's nowhere near as specific or prescriptive (two factors that, when you're not a native AmE speaker, are much appreciated!). cerberusss, thanks for the encouragement :) Now you mention it, I'm pretty sure I've seen the grammar nazi around here before...
