Hey, new person!
Welcome and we're happy to have you round. As far as character stuff goes, check the character closet for some idea on format or structure. Just the general idea and stuff. There are links in the sticky threads that will give you better direction than just milling around aimlessly in our wiki.
Speaking of the wiki, it's really expansive but feel free to ask questions on where stuff is located or to get some idea on what you might need to make your character. There's a lot of information there so just check it out in your free time, eh?
Glad to have ya!
