The great thing about the Guild, is this place is open to all skill levels, and all types. There's something for everyone here. 

Free (Freestyle) is very much designed for newer people, or those that are less worried about Quality. 
Casual - Some quanity and quality standards are present, but most people should have no trouble meeting it's requirements.
Advanced - Much more stringent standards and rules here in regards to quantity and quality. Though sometimes you run into a lot of purple prose. 

Each section has their rules defined in their blubs, and in a sticky for each section. If you're looking for an RP to join, check out each sections Interest Check area, as well as the General Interest Check section.
