@Witch CatWelcome to the strange and wonderful world that is The Guild! Don't worry, most of us don't bite. ;)
The above post pretty much covered the basics. The main thing you need to focus on is having fun. Don't be afraid of asking questions, feel free to experiment around with the different sections, and let all your creative juices flow!
Feel free to PM me you ever wanna ask a question, RP, or just plain chat. I love meeting new peeps!
