Thought that's what you were after, and felt perhaps you hadn't realized the new setup here automatically embedded any X link now, so no embed code required. That's why i said all you have to do is copy the X address and paste it. I did forget to consider it may be different for any not using Firefox, then again the URL copied would be the same so guess that wouldn't matter.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
