I went to the site linda posted, it looks legit to me. I read over it and apparently it is run by the author of a book called Grimorie for the Apprentice Wizard. Iv flipped through that book a few times before. The author is a bit... out there, but he is also extremely inteligent and open minded. The school is geared toowards kids ages 11-18. You have to pay "tuition" while your a member of the site but its a really cheap price. Only problem is finding a way to pay without your parents finding out if they dont know you do magic.
Browse.. more.. try Lightworkers.org I believe is the site.. O_O.. they have different articles.. tons of them. -_- Best thing ever, is teach yourself and find some one in your community to help you. It does not have to be directly in the term under magick.. Most people that are spiritual practice similar methods.
