I had found this site a few months ago MAINTANKADIN when it was formed to be a site for Paladin Tankadins to find or get useful information and feedback on their class other than the troll pages of the WoW forum. I've had it linked here on the site as a Tankadin Guide site as its also quite informative a forum site for Tankadins. You can get good feedback on Tankadin issues from other good playing Tankadins or Theorycrafting Paladins.
I highly recommend it if your a Tankadin to drop by there and see how usefull you find it to your needs. Link here.
Edit: Added site name.
