Revised: 12/30/16
Taking into account that we are now redirecting to the HTTPS version pages of our website, I am revising the instruction on how to embed YouTube videos within forum posts.
In order to embed a YouTube-hosted video within the body of a forum post, any of the following 5 examples will work:
[video]https://www.youtube.com/watch?v=DpjwS0daWrM[/video]
[video]http://www.youtube.com/watch?v=DpjwS0daWrM[/video]
[video]http://youtu.be/DpjwS0daWrM[/video]
[video=youtube_share;DpjwS0daWrM]https://youtu.be/DpjwS0daWrM[/video]
[video=youtube_share;DpjwS0daWrM]http://youtu.be/DpjwS0daWrM[/video]
The following example, a short URL calling https protocol, will NOT work:
[video]https://youtu.be/DpjwS0daWrM[/video]
Irrespective of which link format you choose, you may either manually type the [video][/video] tags before and after a YouTube video address, or you may click on the 'Insert Video' button on the editor toolbar (the one with a filmstrip icon) and paste or type the YouTube video address (minus the tags) into the dialog box and then click 'OK'. Both methods should work fine.
I hope this is helpful.
