Good catch, thanks. Unfortunately that information wasn't in the email.

Now, do hyphenated words count as one word or two? Do numbers count as words (e.g. is "12 years old" three words or two?) If I write 1,000 words but concatenate them without spaces, is that still considered 1,000 words, or one single word?

I don't know of any English word counting algorithm or MoS that does not count "12" as a word, do you?
