Currently, we're envisioning:

• Novel Writing Month - 50,000 words
• Novella Writing Month - 20,000 words
• Short Story Writing Month - 5 stories of at least 2,000 words each
• Poetry Writing Month - 1 poem per day
• Blog Post Writing Month - 1 blog post per day
• Graphic Novel Writing Month (maybe?) - a 50-page graphic novel
• …or, of course, a custom goal.
