I actually have someone else I'm working with on this now so it's already started.  But if you want in I can ask my partner if she's willing to pull this into a small group RP instead.  

Though to answer your question: I always play in the casual section, but sometimes I use and expect "Advanced" level ideas and lore.  I don't like the advanced section, though, because there's sort of an unwritten expectation over there that every post must be a certain length.  I personally believe that in some situations that's not only unfeasible, but actually worse writing than doing a shorter post.
