Server owners and popular players, who share mod configs.
I'd be grateful if you will delete uuid parameter in the shared version of IC2NuclearControl.cfg.
uuid is random value, I use it to estimate addon popularity without logging of logins or any personal information. But as I can see, multiple players use same uuid.
Interessting. Why didnt you just make a second File outside the configdir in the .minecraft-Folder for saving this Data?
