As promised, here is the first set of hints for puzzle number 9. I should also point out that one person has sent in solutions that use all of the letters (and are totally unrelated to my starting sentences, so clearly there are other possibilities). Of course, one of the solutions is not actually intelligible, but it is still a set of real words that use all of the letters.
Anyway, this hint gives the number of words in each "official" sentence (in other words, the one I started with to come up with the letter list). On the weekend I will release the number of letters in each word along with the punctuation in the sentence, before giving the answers next week. Of course, one should not feel constrained by the hints. Novel solutions are still very much appreciated. Please just point out whether or not you used the hints in coming up with your solution.
1.) A A C G G H H H I I I L M N N N O O R S T T U W Y
Six words, one is a contraction.
2.) A A A E E E E E E E E E F G H H H H I I N O O P P R R R R S S S S S T T T T T V Y
Eight words, none are contractions.
