Another reason this is unappealing is (no offense to any of the RPers, especially those of you who have decent description - Kingdra and krackerjack) that there is a lack of grammar.
Look, the forementioned two have good description, but no one likes a wall of text. Also, although descriptions are provided at times, they're bland; it doesn't really matter about the _length_ of your posts, it's the _quality_ of them. I might have like a 1394081-3498 line post but it still doesn't change the fact that I have no punctuation or capitalization or variety in words (I'ma looking at you, krackerjack - basic words are good but go for more) will totally blow the fscking thing up.
EDIT: Another big thing is bunnying. Bunnying is the control of other characters. I hate bunnying, but I'd allow it if people stated they were given permission. Which you guys don't really do =x, but that's my opinion...
