Wassail!
What kind of Witchcraft are you looking for exactly? Or maybe I should say...sorcery (magic). There is chaos magic, ceremonial magic, Witchcraft, and of course the way of the wica just to name a few. The latter I know close to nothing about.
I will not teach you anything but I can lead you in the right direction. If you are interested in the ways of the Hollow Hill I suggest you go
here where you will learn some things on the Crooked Path.
For Chaos Magic, I know very little about only that it is Chaoticly found out about (go figure) but there are members here that use it so you should have no problem there.
Ceremonial...hmm...well there are MANY things on ceremonial magic. It depends I think on where you want to go with it. I suggest picking up a copy of the Key of Solomon (please, PLEASE do not summon any of the Goetic demons until you know what the consequences are!).
Anyway, I hope that helps.
FFF,
Angus
