We’ve had a couple of questions concerning how to embed certain types of media into your posts, such as YouTube, Vimeo, Vine and the like. I think a big part of the problem is that we don’t have a button for it in the editor. Also, some people fear change.
All you have to do to include a YouTube movie is paste the address of the YouTube vid into your post.
The forum pros usually employ the old Control-V paste keyboard shortcut. Right clicking the edit window brings up unhelpful table options.
The forum will automatically determine that this is a YouTube vid, and spit out the correct code to show it in your post.
This should also work for Vimeo, Instagram, Vine and Screenr.
