Similar to Embed Instagram which I also just added.

How to use:

1) Get the Vine URL

2) Take the part after vine.co/

3) Use that part in a tag like this: [vine]v/bJK51E9V9Dp[/vine]

So take this Vine video:

http://vine.co/v/bJK51E9V9Dp

The relevant part is v/bJK51E9V9Dp

So you do:

[vine]v/bJK51E9V9Dp[/vine]

And it looks like this:

 

https://vine.co/v/bJK51E9V9Dp



Enjoy!
