Over the summer I launched an ARG mystery for the Theorist community to solve. It required people to work with each other to piece together the clues hidden in our back to school merch launch. Today I am going to show you how it all was put together because this was only the BETA TEST! If the Theorist community wants it, we will be making more of these treasure hunts, so keep your eyes open. You never know when the next hunt will begin...
