Welcome to Spells of Magic, you should have recieved two messages, one from one of the moderators, and one from the Petrarca (the Administrator). The moderator message will contain some helpful suggestions. The first thing you want to do is learn the site rules, there are different rules depending on some features.
Now, if you are a beginner in magic, I would suggest you learning the basics. They are kind of the training wheels in magic, they will help you understand the possibilities and the fantasy in magic. There is a lot of helpful information and a lot of misleading information, so you got to use common sense when reading and or practicing. There are two threads I recommend; one is, AwakeTooLong's "The Basics: Expanded", and Starries "Starting Out". You can find both of them in the General Information in the Forums.
