A very interesting proposal, one I find especially peculiar to think about. I've never tried to classify myself into a roleplaying standard before, and as I read the two listed categories I find that I lie somewhere in the middle ground, so conforming to either one will be a rather new sensation.

Leaving my personal standing and quirks aside, I can see how your categorization can help keep the two standards seperate, yet not overly so. It would be simple enough for someone to, per se, 'try their hand' at the Advance style coming up from a 'casual', and equally simple for someone to 'relax' and be a more laid-back casual. The only real stipulation being paragraph limits and tighter grammar restrictions- the character limit is rather superficial.

The simplified character sheet is certainly simpler xD I can definitely see this idea of combining the two 'classes' of roleplayers panning out.

I'm sorry if I comment on something incorrectly or in a strange manner; I am not used to having roleplay categorized in such a manner (based on skill/length... The idea just seems...segregational to me), nor am I used to the forum setting.
