I could never really get into Wicca, like lots of people it was the first thing I had access to- but this was over 20 years ago, and there was ONE book I could get my hands on. Anyway, it just doesn't speak to me much. I know the basics, if somebody really needed an overview I could give it to them, but that's about as far as I go that way.
One thing that has always puzzled me that you might be able to shed some light on: many of the Wiccans I've come in contact with through the years don't do any sort of magic aside from your basic worship rituals. Is it just general misunderstanding of what they think the Wiccan Rede is (I know there are way to many who think it's just the law of three/seven/etc) or is there something else?
I mean, personally, I learned by jumping in there and getting dirty. And dealing with the consequences.
