Upload
Upload your results
The uploader app does this for you. If you don't have it, you can send your file by hand here.
Where is the file?
Look in your game folder:
World of Warcraft\_classic_beta_\WTF\Account\<ACCOUNT>\SavedVariables\Thorim.luaInstead of _classic_beta_ it may be _retail_ or your Forever folder. The game updates the file when you log out or type /reload.
Only your Thorim results are sent. Nothing else leaves your computer.
