If you have a Facebook page and have never used Woobox to help you randomly pick winners, let me just say, it's pretty awesome!
I made a tutorial in August, and a month and a half later, I finally got it on YouTube. Hope it helps you out! Is there a different way you use to pick winners at your Facebook page?
I've also compiled a playlist for my few videos with tips for teacher authors. Click the image below to watch them all. And please share your tips, too! I'm trying to work smarter, not harder! How about you?
