Just for the future, you use [youtube]<letters at the end of the url here>[/ youtube] to embed a youtube video.
For yours it would be [youtube]rmUmQfkGVpo[/ youtube] without the space in [/ youtube].
For anyone else who sees this:
[youtube]rmUmQfkGVpo[/youtube]
OT: You sound really bored in your videos (no offense).. It would be really nice if you sounded like you were having more fun. Also, I really didn't know what you were supposed to be doing, care to explain?
