Honestly, you're not likely to catch me "messing around" with Ouija, unless I have to, in the first place. I've already dealt with enough of it that we (Ouija and myself) don't get along very well.
I don't know what to think about Ouija. I've seen sessions with clever answers to questions so.... But, in another way, why ouija and not mediumnity (more easy to Spirits). So... I have a definitive opinion.
