Have you ever wanted to edit a specific book, or just a type of book? Now you can! Just specify the book or type of book and add in what you wish wherever you want on this forum! I've always wanted to edit those little books for kids, introducing them to animals... specifically cats, dogs, gerbils, hampsters and horses, the first four of which I have experience with. They say things like "don't pull Kitty's tail", but I just want to write in the consequences, like "Or Kitty will take her claws to the hand pulling her tail and you will have a bleeding stump of a clawed wrist where your hand once was".
Dogs: "You can take your dog on nice, long walks as you both enjoy a slow stroll through the park." My addition: "Unless your dog is a Siberian Husky or other sled-pulling dog, in which case you'll take him on long, painful walks which involve dragging across the asphalt until you bleed enough to attract a mountain lion..."
Gerbils: "When you get your gerbil trained up, he'll be sociable, friendly and nice." My addition: "Before he's trained, he'll be an absolute nightmare and bite all your fingers off."
Hampsters: "When you first take him home, make sure he has a clean cage." My addition: "Because you want him to be happy, as he'll die in three weeks very suddenly."
Horses: "Approach a horse slowly, as horses are easily spooked." My addition: "Especially by Nazgul."
Heehee. I'd also like to add footnotes into LOTR... when they mention Elfhelm seeming to understand, I'd put "Understand about MERRY! The Hobbit! This has NOTHING to do with Dernhelm!"
And when Eowyn finishes the Witch-King, I'd dearly love for a footnote saying "It was Eowyn, not Merry, The Witch-King, Tom Bombadil, or Westernesse who killed the Witch-king, much less Frodo or Legolas!"
(I once made a comic entitled "I'm no man, now gimme money" which involved Legolas being shot... long story.)
