Another issue is that if you are not legally an adult it would be against the law for any adult to teach you about Wicca, which is a religion not a magical practice, without the express consent of your parents. So it is unlikely that you are going to find a teacher unless you are over the age of 18.
That being said, there is some information you might find useful in the threads at http://www.spellsofmagic.com/read_post.html?post=580909 And you might also want to read the thread at http://www.spellsofmagic.com/read_post.html?post=637268
While I do not teach on-line I will answer specific questions if you have them. I've been a practicing Wiccan for some 30 years and a High Priestess since 1996.
