UH-HUH. Looking over the stories section that they already have (well, skimming 'cause I'm too lazy to read), it seems that probably Simple would be an appropriate stage. From what I can see, they're not too good on the grammar scale, and those that are use basic styles of writing. With a bit of advice -- and if they follow that advice -- they can get a little better, and there're already some good authors mixed in. Problem is, there's, like, 19 stories actually posted, and one of them is Alaska's lol. I'd suggest Basic anyway, as I'm judging from what I saw that that'd be an easily-achievable goal for maybe all of the people who've posted something up.
