I would not try this. I had two friends who used to do this quite often, both of them had nothing but bad luck and the girls home in which they used it had tons of unexplained disasters right after they started using it.
Whatever "energy" or "entity" they brought forth was not a pleasant one, and they couldn't get rid of it. They won't tell me what happened the last time they used it, but I know it scared them to death and they threw away the board.
Think about it, your asking questions, but you have no idea who is answering you. Would you take advice from random strangers on the street? Probably not. So, why would you put your faith in asking "something" you can't even see, to help you. You may get "something" to respond, but it may be more than you bargained for. Be careful.
