I had that too, until I turned into a demonic mistress of perfection. No, really, I just ask for a text sample whenever I feel doubtful. 

Since asking everyone directly through the OOC, out of the blue, can be scary for other players, just PM the ones that posted a character. Ask them to provide you with a text sample for quality purposes. As the GM, we have the right to do such a thing. You can also introduce me as a sort of co-GM or helping hand. If you want, I can be the one in charge of disciplinary measures! :O Yes! YES!....Hrm-- I mean, Bunnies and butterfly and chocolate cupcakes...anyway. Yeah, I can ask them if you want em to.

P.S: I really wasn't mad or anything, I actually love the idea of laying back and just giving a helping hand. :)
