First I have to mention this is just a game not to be taken too serious. Have fun with it and creep yourself and friends out.
The game has audio to add a little more creepiness. I suggest playing on a dark and stormy night.
Now comes with a free spirit attached, start up the App, go to the board and just wait to be contacted Mwhahahaha.
If you want to add your own messages their is a secret MOON button on the menu screen to do this. It will save the messages on your device so you can act all innocent when starting it up to show friends then freak them out by having messages with their names.
As in the secret menu options you can enable the KNOCK KNOCK KNOCK feature, so when you return to the board, ask your question then knock/tap three times and you will be answered. Lots of fun to be had experimenting.
If your spirit gets out of control, hold your finger over the candle to cleanse the board.
