When you're composing your blog, there's a little button up at the top that you click to add a video. It's like the one you click to add a photo, only it looks like a movie reel.
I didn't have that button! I had switched to the new editor and for some reason they removed that button. Crazy. Anyhow, I switched back to the old editor again in settings and now it's back. So now I'm off to post cute videos.
Leave me a comment - please!
