You know, I write essays to word counts all the time, and I've never mistaken character for word count--which is obviously what I've done.
My first pass at an outline was about 5 times longer than what's here. I then spent two hours whittling it down to 500 words... uh, characters. Then copy and pasted a couple entries here into word and AGAIN read character instead of word count. Clearly I've managed to suffer some form of head injury without noticing.
