For those of you interested in Hearthstone, (thanks to @Adam for the request), we now have the ability to display a 'tooltip' popup of any Hearthstone card by linking direct to whatever card you like on www.hearthpwn.com
For example, if you were to hover over this link here for Ysera, you would see that a popup of the exact card would appear without having to go to the site right away to view it.
To achieve the 'gold card' tooltip, all you need to do is add #gold to the end of the url like so: http://www.hearthpwn.../495-ysera#gold
Format for doing this:
[url="enter your card url here"]Card Name Here[/url]
This can be useful for guides and so on for displaying cards onsite
