I. Read ALL of the regulations. I don't know how much more I can stress this. You should read all of the regulations, and you should read this guide as well. If you don't read the guides and regulations, how will you know what's available and what you can and cannot do?
II. Make your character. Before you do ANY kind of role-playing (except for OOC) you MUST make your character. Before you make your abilities or spells, you must make your character!
III. Explore. Role-play, make abilities/spells. I don't care! As long as it's within the regulations and you feel comfortable doing so, I and the rest of staff are fine with it!
