When you're writing a new post/thread in the advanced box there is a YouTube button in the controls at the top of the box. Click that and it'll give you something like this [you*tube][/you*tube] (no asterisks) Get the code for your video and stick it inbetween those two codes ([you*tube]codegoeshere[/you*tube]) Without the asterisks
Just tried playing and that worked. Try it out hun see if I messed up in explaining lol
