Copy the address...type [youtoobe]then paste the address and type[/youtoobe]
only spell youtube right (I had to misspell or you would not see what I typed)
this is the address:
http://www.youtube.com/watch?v=Y4Y7GMPJO64&feature=related
so:[youtoobe]http://www.youtube.com/watch?v=Y4Y7GMPJO64&feature=related[/youtoobe]...but then go back and and erase the part in quotes here:"http://www.youtube.com/watch?v="
so you should have for this example:http:Y4Y7GMPJO64&feature=related
between [youtoobe]and [/youtoobe]
like this:
[youtube]Y4Y7GMPJO64&feature=related[/youtube]
