This is the first Version of my Diablo 3 Tooltip for WordPress. It offers a smart way to include the neccesary 
item JS only when needed. In addition you can use shortcodes in BB Style like [d3]item name[/d3] to insert a 
item information link automatically.
Things to Come: 
As I said, this is the first version, I future the plugin will be more enhanced and using PHP JSON instead of 
JS item rendering so you can cache the item information locally to improve the pagespeed. You can find a 
complete list of upcoming changes on my blog in this posting: http://goo.gl/v6RP0
