Hiya!
Colour. I *hate* having freaking full colour "background for every page". Absolutely loath it.
You know there's the wonderful thing about PDF's... you can set them up to let the user hide stuff like fancy full colour backgrounds, boarders, etc.
Please, for the love of all that is Just and Good in the world... re-upload the PDF to DriveThru with the ability for users to disable the colour background, and also make a b/w version? I have all my HARP books printed out and spiral bound....nice, easy to read and easy to annotate as needed on simple, white paper.
