If you want to do like the cool kids and actualy show the video in your post follow me:
type the [ bracket next to your letter P key, then type "video:youtube" without the quotes and then end it with the closed bracket ]
[video:youtube]
next paste your youtube link
https://www.youtube.com/watch?v=DKxZY0DIxIk
and then end it with the bracket[ with /video and end bracket
[/video]
It will look like this:
[video:youtube]
https://www.youtube.com/watch?v=DKxZY0DIxIk [/video]
Now if I take the spaces out between the ] http...k[ it then looks like this:
