I've just begun learning the different meanings of the Runes, and when googling information on them, came across an interesting...approach? The owner of one website (I forget which one) said that they didn't work with reversed meanings. So, even if Berkano landed backwards, they would interpret it as "right side up".
Their reasoning is because they don't work with reversed cards in the tarot (and I admit I don't either), and that to work with reversed Runes they would all need to be able to be reversed, but some like Sowelo can't be.
Has anybody else ever heard of this or worked with the Runes like that?
