Never use the board to control others. Do not let others use your board when you are not using it. Keep the board in a special place of your choosing. Do not get addicted to the board. Using a ouija board is not a 'medium' for everyone.
Some people get it immediately others never do.
This seems to have no bearing on whether one is psychic or not. Many psychics can't work a Ouija Board. With experience you can learn to channel your deceased loved ones and entities from other realms. Some days the board may work for you. Others days you may get no responses.
