Aww, thanks Barb. I'm also wondering if we hit some sort of a thread limit. I know this had happened with the Word Association thread.
However, since I was posting and trying to include the YouTube code, I'd better make sure I know what I'm doing next time. Usually when I add a YouTube video in a post, I just add the URL, but noticed some members must be including the code so the title and play button shows in the post - much nicer!
That's what I think I messed up, so I will also make sure I know what should work.
I think I just copied and pasted the code from the Embed field in YouTube and maybe I needed to add the pair of tags before and after the URL, ie [youtube]....[/youtube].
Maybe someone like GillR or Altara33606 will let us know what they use or I'll ask in the Help forum.
