I'm a bit scared...I can only type in 6 paragraphs each post, is that considered high casual?

If I may ask, why do you prefer messaged cs's rather than posted cs's? 

Edit: now that I think about it, high casual may be too high for me. Not that dedicated enough to go 6 paragraphs.

I see this being a big problem with people attempting to define high casual or advanced.

I've been in a few advanced RPs myself and I've never had to consistently post 6 solid paragraphs, ever. I've never posted below 3, but that's my personal thing. I could have literally flown by just as easily posting 2 paragraphs a post.

It's never about the quantity of a post--never about how many paragraphs you can dish out--it's a about your ability to progress through a plot. It's about knowing your character and where they may go. It's about reacting to situations accordingly and developing both the plot and the character from it. You can accomplish that with 2 solid paragraphs of detail.

Character development and plot progression are what high casual and advanced GMs care that you know how to do. And doing that in a way that keeps you and the other RPers interested in what you're writing.

Focusing on the length of your post rather than the quality is going to clog it with filler--unnecessary info. Nothing's wrong with filler (I can be flowery and purple in my writing too) but jam packing a post with it is going to drive a person insane. I can write 10+ paragraphs of filler, explaining away the setting and the appearance of my character and expanding the detail of their actions, and that's a sure fire way for the GM of an Advanced RP to pull me aside and ask if I've either been drinking or gotten a little in over my head.

Two paragraphs. That's 10 sentences total. That's a solid length that gives you the perfect amount of room to drive a plot forward--it's also enough to get your characterization down and set the stones you need to move a character forward, as well.

Oh and a good grasp on utilizing the written language well enough to put all of these elements together. Not novel, best seller level of artistry like some people think. At the least, an 11th grade grasp of the English language to college level will suffice. More is great, but never necessary.

I mean, I've been in high casual RPs since I was a sophomore in high school. The expectations aren't as lax as casual but most GMs don't expect you to be able to write an entire novel's worth of material.
