Here is what you need to do to post an imbeded video.

Get the link.

You will get a window that looks like this.

Paste the link in and click any blank space in the window and you will get a preview. It may take a couple  seconds for the video to show up in the window. Click 'Insert'. Your video shows up as a colored box. This is normal.

Click 'Submit' and you have your video!

Ah, thank you.  Not sure if my link had an 's' in it, and also I didn't try to use the other formats because Taz made it sound like the TinyMCE was the only format that worked for posting on the forum.

I'll have to remember that for next time.

The https address is the key. The site can't link to your account and won't display the video. I have done this a couple times and probably should have mentioned it here but didn't really think about it. When linking videos the way I show above you should be logged out of youtube so you get the raw link without any extra charactors linked to your account.

Makes sense.  It was a bit confusing, but the link I was using didn't have the https on it.  Just http.  But I'll get the direct link from the video (not the youtu.be one) next time I try to post one.  Thanks for the tips.
