Thanks, Lance, for the reference. Sketchy, but it probably covers all the difference there really is. I'm assuming that amongst is similar enough in usage that I can let it drop for now. (Never did actually need to know, but I get curious about things sometimes. Like how come in the UK inserting an e in the middle of judgment--an act that makes eminent sense--is common but not universal, but in the US is heavily--but heavily!--frowned upon. Or, for that matter how come the Brits never yielded to the American dictum that putting a period or comma outside the quotation marks is a cardinal sin.)
