LOL...I never think about how large it is when I start writing. When I get on a roll, I don't stop until I feel it is done. At least I edit what I write three or four times before I post it. It will be grammatically correct if nothing else. My longest post in the RPG forums was 8 pages long on MS Word (Times New Roman, 12pt). It had 55 paragraphs. But that was an NRP about five years ago. I never think about the length. I just go. But to limit myself to 4 or 5 paragraphs sounds excruciatingly painful. I could write four or five paragraphs here in the OOC.

EDIT: If my post is too long for some folks, I am not apologizing.
