This is probably how I would do it:
Animation
× Animation Freestyle
× Anonymous Animation
× Pivot Animation
- × Beginners Hall
- × Intermediate Area
- × Veterans Hangout
- × Elite Zone
× Flash Animation
- × Beginners Hall
- × Intermediate Area
- × Veterans Hangout
× Organization
× Requests
× Tutorials
× Animation Chat
The ranked sections here being under sub-forums. It would make the index look a lot cleaner in my opinion. If people are still very much against sub-forums then I would probably just put Freestyle, Anonymous, Organization, Requests, Tutorials and Chat in a separate 'Animation Extra'-section or something like that.
