I eventually got mostly all of them yesterday. I confess to having Googled some of the more British answers.

Nigel, if you read this, #12 and #13 reversed, which is actually pretty funny; the tu(y)po IS a typo; one answer is past tense and should be the infinitive. In one question, I deserve to be punished for reading comprension laziness. I also get the distinct feeling I'm missing something in a couple of responses. Only time (and Nigel) will tell.
