I think that there may be a bit of confusion here. You might want to read the article in the Wicca Forum on what Wicca is and what it is not at http://www.spellsofmagic.com/read_post.html?post=637268 . Wicca has nothing to do with casting spells, in fact many Wiccans seldom if ever cast a spell. Wicca is a religion with specific beliefs and practices. You can find a great deal of information about Wicca at http://www.spellsofmagic.com/read_post.html?post=580909
It seems to be a common misconception that Wicca is all about casting spells, and I supp;ose we have the TV series "Charmed" for a lot of that misinformation. You can easily cast spells without being Wiccan at all. But if you're going to be Wiccan it would behoove you to investigate the beliefs and practices of the religion to see whether it fits with your own views regarding the Gods, etc.
