I just learned that November is National Blog Posting Month. The only requirement is that you post every day.
It doesn't look like I will be doing that, since I will need to produce at least 1666 words a day in order to complete 50,000 words in one month through National Writing Novel Month.
According to a family member, yesterday was Paint Your Own Portrait Day. I can't find the link for it, and no, I didn't paint my own portrait, though I have done several stylized ones photoshop.
