Wuushu has been a busy chap these past couple of weeks and given the WoW database WoWDigger.com a complete makeover. He’s also thrown in a few new features as well to enhance your experience with the database such as in-game items, bbcode items, improved talent calcs, improved displays on things such as rep, items, comments, the list goes on.
The character profiler has also been given an interface makeover to make things more intuitive and easier to use, including detailed instructions on your profile page to explain how it all works. The interace is more what you are used to when playing WoW so you’ll get the hang of it easily 
The first skin for WotLK is now live and kicking as the default and another is on its way. Make sure you check it out!
