If you have a novel idea you're invited to join NaNoWriMo for a breath taking month of writing. Think first draft ... quantity vs. quality ... a chance to write the novel you have been putting off. Forget editing as you go, instead the goal is to create a 175 page (50,000 words) first draft. Its free, the website is great, and there is round the clock support online.
