Thanks, that's very helpful. This should be a sticky, in my view.Copy the URL of the YouTube video. In the reply window, click on the toolbar icon that looks like a black H on a blue background, usually the second icon from upper right - it's supposed to be two frames of film. In the window that pops up, paste the video URL, then click the OK button.
It is available. The first post in a new thread, a reply in an existing thread, and editing a post you've made all have the formatting toolbar, with the film frames described in post #3. You just have to be entering text for the toolbar to be enabled.The insert video option is not available for the first post of a thread?
