Okay, I think the easiest way to do this on my phone is to make general statements for everyone, even though I prefer to be specific.

So, if it were advanced, I would expect no more than 3 paragraphs (though more would not be discouraged). I, personally, don't care for purple prose. I just care about character development and continuity (so reading and understanding time and space of all characters).
I prefer proper grammar, and I will be more than willing to enlighten anyone on the subject should they care for it.

So, if it were placed in advanced, I have a feeling that no one would have a problem. I'm not really strict when it comes to advanced.

As for group size, I'm more than determined to keep up a large group, but I understand the hesitations. But I'm really hoping for everyone to be committed to play their part and communicate respectfully and effectively. 

But I'm open to CSs being PM'd to me, though. I'd like to know if everyone understands the mechanics I'm intending to implement. [@Loony] has already PM'd me their concerns. I would like to open up conversation to this topic next before we really get started. ^^

EDIT: oh god, the horror of my grammar on the phone. (〒︿〒)
