Here are just a list of WAR sites, if you know of any more, feel free to post them up and share.
WARDB - Warhammer Online Database
This site is the WoWhead for Warhammer. Clean layout and provides everything from a character search to item search. Also it has a Career Builder and Renown Builder tool, definitely something all WAR players should check out.
Warhammer Forums - Warhammer Online Age of Reckoning
There are many WAR forums, but this seems to be the most active one. For those who may not know, there is no official WAR forum. This forum is very good to chat and discuss if anything is wrong. Its a very helpful community
Mythic Entertainment | Warhammer Online
Lastly, the Official WAR site, if you are a new player and curious what all the buzz is about, check out the site. They have very entertaining podcast's starring their developers.
Thats about it!
