ARG developer finds out his email hint system doesn't work anymore because young people don't know how to use email

After Hours is an Augmented Reality Game, which means its puzzles have to be solved with information from outside the game—mostly from your web browser. One puzzle apparently involves combining Brownsville, New York's zip code with a phone number to find an ISBN code, which leads to a book you need to look at the back cover of on Amazon, all so you can find a password hidden there.

It's pretty tricky stuff. Fortunately, there's a hint system. Unfortunately, that hint system also exists outside the game.
