just choose what you want to say and let it come straight from your heart.
i know how cheesy that sounds, but that's what i did.
my mom wasn't too fond of me putting in my email address or my address, so i couldn't.
but i just put my name on it.
but since mine's a book full of stuff, it's kind of different than what you're doing.
you can put email or address in if you wish, but i'm not sure if david would be able to reply.
good luck writing though.
