[@Vor] I agree. I've always thought that free roleplay was indeed more of a time-allocation thing and advanced was simply put, labeled wrongly. They're not more advanced writers per definition (though, often, they are so in practice). I think the 'differentiation between the levels' here comes also from this time commitment.

Simply put, more time spent writing = faster adaptation of good writer = easier to become a good writer. The advanced roleplay tab doesn't indicate solely that if you write there, you're a good writer. I've read many non-good posts in advanced. I don't read much free roleplay, but in casual, I've seen some absolute masterworks. I think a fair part of that is also the interactivity. 

Roleplay isn't solely about writing anyway. It's also about interactivity (for me) and understanding story-telling. You can be Tolkien, if you can't work with other people and/or tell a story in an interesting way no matter how good you write it, I'd be inclined to think you're not as good as you write.

As long as people are having fun, though, I think it's all fine. The discussion is growing old for me and frankly I think both sides to this story are just being stupid. Just let people have their playgrounds, right?
