Magic Forums

I'm new here and I'm currently going through a transisitionary phase. I have many questions that I don't know where else to ask except behind a username and in a seemingly acceptingly atmosphere I have many questions revolving mostly around Wicca. I'll number them.
1)do I need a book of shadows.
2)can my BOS be digital or is that supposed to be physical?
3)do half the spells here apply to me/work?
4)do I need to go to wiccachurch?
5)if someone asks me what my religion is, do I say I'm a witch or wicca or what?
6)it sounds like everything I could possibly want out of a religion, but will people start disliking me for it?
7)general advise?
8)is the pentacle/star thingy the religious representational symbol,or is that something else?
9)is spell craft even nessisary? Id like to do it but I don't know the limitations or what I should do with it besides general goodness.
10)how was your day and what's your favorite non alcoholic drink?
Thank you.
