This may be a bit off topic, but I used one of the sales letter creators to play a game with my 10-year-old dd. We filled in the blanks as though we were playing "Mad Libs". (In case you are unfamiliar with Mad Libs, it's a game in which a story is written with a number of blanks that only contain the type of word that should be placed there, such as noun, adjective, etc. One person calls out "noun" or "verb" or whatever the case may be, and the other person, who knows nothing about the story, will give the type of word to be filled in. They often wind up to be very interesting. An example might be something like, "last night my pants put out the fire to be picked up by the garbage company, then came in and sat in my favorite watermelon.")
Anyway, we did that with the sales letter creator, and the results were so funny, that she took the resulting "sales letter" to school to share with her friends.
That's one of the fun things about kids - they find just about anything silly amazingly entertaining.
