Keep Calm, Canter On had a good chunk of it's first chapter rewritten for the sake of capturing Fancypants' character a bit better.

Best Cupcake Ever had a line edited so that it made something resembling logical sense. I'm not sure how I typed "with a matter thud" without noticing anything glaringly wrong.

And on the subject of Best Cupcake Ever, I'm obviously new to this site, but I'm pretty sure tracking a one-shot isn't really the best idea, given the fact that, aside from possible spelling fixes later, it's not getting any real updates.
