The current, updated version can be found HERE.
This version of Enhanced Tradeskills (Fan Update) is compatible with Wrath of the Lick King Beta ONLY.
IMPORTANT NOTE: When upgrading from a previous version, you will need to delete your SavedVariables file for this addon. It can be found at: "DriveLetter":\Wrath of the Lich King Beta\WTF\Account\"AccountName"\SavedVariables\EnhancedTradeSkills.lua
"DriveLetter" = Whatever hard drive you installed the game on, for example: C
"AccountName" = The login name of your account.
Failure to do this will hang the game more often than not.
I may have left out some of the buyables, so if anyone finds some, please let me know.
