Tips on Posting Youtube Videos:
1. Copy the URL of the video you want to embed. Don't use the URL that YouTube provides when you click on their 'share' button, but rather the one that appears at the top of your brower window.
2. Go to wherever in your post you want to place the video;
3. Click on the 'little blue filmstrip' icon that appears just above the box where you enter your message (it's the second one from the right);
4. When the pop-up box appears, paste the URL that you copied into the window.
5. Remove any 'excess baggage' contained in the URL. This would include any 's' that might appear after the 'http' at the very beginning as well as the '&' sign and anything else that comes thereafter. For instance, remove all the red that appears in this URL:
http
s ://www.youtube.com/watch?v=w7XSsY9A87A
&feature=youtu.be
6. Click on the "OK" button on the pop-up; and,
7. Click on the "Preview" button below the message box to insure your video appears correctly before posting.
