I personally like witchvox as a good source of material on our faith. There are others. Do a search on Witchcraft or Wicca or even Pagan and you will get very good sites. After I went back to wicca, I got on the net and found several other people in my area who are also teen witches. I have been able to meet so many friends.
Some people say there are evil influences on the net.
I think that there are very few evil influences. However some Christian sites come very close to being evil. Especially those who spew hate talk against Gays and non Christians. Sorry if this is a bit jumbled. Information on any subject possible in record time.
