Instead of taking the 50,000 word challenge, I am simply editing this year. I've taken on proofreading responsibilities for a few other NaNo projects. During the Writers Camp, we're posting stuff nearly as soon as the first draft is written which is considerably different than the way NaNoWriMo projects are traditionally handled, so I help where I can.
Right now, I am keeping pace. It's entirely possible that I will get swamped during the last week rush. If that happens, so be it.
