To get postive results one must understand about why sometimes spirits become earth bound and understand rebirth and reincarnation. But do be careful in contacting a loved one. Who you are talking may or may not be who that claim to be. Testing them might not work because spirits can read your mind. If you do test them keep your mind blank. Also if the spirit starts telling you to do things no matter how harmless they may be DONT LISTEN! Stop right then and there.
They say that if you trash a Oujia Board it will reappear the day you move or that the board will not burn if you try to set fire to it. I'm not sure if it's true but I have trashed so many Oujia boards but not one single one has returned. I think you have to really use the board for this to happen. The boards I have trashed I only used once or twice.
Oujia boards actully maybe helpful at times. They can help you find lost objects, get advice, and learn about the "other side." You also maybe able to even find a friend. After using the board you might develope pychic powers and better awareness of the world around you. You will also understand death a lot better.
I do not recommand you to try to use the board until you learn how to fully protect your self from harm.
How to use the board
Get at least 2 other people with you, one to write and you and another use the pointer. Lightly put your finger tips on the pointer. Ask if everyone wishes to talk with you and follow the pointer with your fingers. Don't press hard or the spirit will not be able to move the pointer. The reason for your fingers to be on the pointer is because spirits need human energy to be able to move things around easier. Like automatic writing. The spirit used the pencil that is in your hand to write.
You don't have to have any candles or wierd music on. It's best not to have distracting music on anyway. Say a prayer over the board if you wish. Don't let small children near the place where you are using the board. Even though they are not using the board doesn't mean that they can't get hurt.
Once a message has been written down try to see what it says. Sometimes spirits misspell words or can't speak English every well. The message may even be backwards.
