while having someone to help you through sticky situations is nice, you don't really need a teacher. books, articles, and the forums should do just nicely. when i started i had books and articles online. one day about 6 months in a girl in my religion class came up and told me she was third generation wiccan so if i needed some books she could lend them to me. i asked her how to correctly pronounce some stuff, but other than that, we traded information. she told me about the occult shop i frequent, in exchange i bought her some books. never really had a teacher myself, it just comes down to how much you want to study, and occasionally asking people for help.
that being said, what exactly did you need help with from a teacher?
