I've seen many people just post a link or failed to use the YouTube wrap button so heres how to do it legit.
Pretty sure someone posted this but it's been forgotten...
1. Get the link
Ex:
http://www.youtube.com/watch?v=uf9sI...ture=g-all-lik
2. Copy the red part (after the =)
http://www.youtube.com/watch?v=uf9sItcBsjw&feature=g-all-lik
3. Then Wrap it
4. It should look like this now:
PHP Code:
[INVALIDYOUTUBE]uf9sItcBsjw&feature=g-all-lik[/INVALIDYOUTUBE]
[YOUTUBE]uf9sItcBsjw&feature=g-all-lik[/YOUTUBE]
