What have you got to lose? Nothing, so give it a try. At the worst you come off with a rough draft of around 50,000 words. Don't worry about technical issues or plot or grammar, just let the words flow from your finger tips. You only have a month to write so loosen up and type whatever comes to mind. I'll let you know how I'm doing, you can let me know how you're doing. Together we can do it!
