Oh wow, I love a good challenge. A few Q's:
1. Do we have to post the words on Authonomy? I try to wait until I edit somewhat before I add, plus I write long hand as my first draft. Or can we maybe post on a blog, ect, and share the link?
2. Can I start tomorrow? 
1: No. All I need is an estimated word count of how much you have written during the week. No need to share the words with anyone unless you want to.
2: Yes.
Will add these questions to the main post
And adding your name into the list!
