glad to have another new member of the family here.
I agree with what has been said in that 1) spells aren't the most important part of being Wiccan/Pagan and 2) spells you write yourself are going to be much more powerful because, in reality, the spell starts (and the transfer of your energy to it) not when you physically begin to enact it, but when you begin the preparations for it.
As for herbs and plants, I'll be happy to help you out on any questions you may have. I had tried starting a once a week post on a different herb at one point but, unfortunately, life and work has been keeping me away from the boards a lot so that didn't come to much. But if you need to know about a specific plant just post a question about it - I know that I'm not the only one here with a vast store of herbal knowledge so I'm sure you'll get lots of responses.
