Is there a selection I need in my settings? I used to see them fine.
Since introducing the [YOUTUBE] tag to the forum there is another altervative available in the newest forum version.When writing your post, the links or in this case the icons to post videos are indicated by the red arrows in the attached image below.
The one on the left is for self-hosted videos where I never tried it but I suppose that you must include URL of where the video is hosted.
The one on the right is for You Tube hosted videos - You must enter only the alphabetical code that follows the = sign in between the you tube tags.
