By the way, to embed a YouTube video here, do not use the embed code you get from the “share” portion of the video. Just copy and paste the complete video URL on a single line, no spaces or content before or after. Rob mentioned this previously here, but I want to spread the information as much as possible because it took me a good 10-15 minutes to finally RTFM and get it right.
