Ok, thanks for the reply. If the support team already said it will follow the pattern of minecraft, not anything else to say. Thanks for the reply anyway. I like the work of the team Tekkit, I had this idea, I thought it would be something simple. Well I've seen that I was mistaken. I apologize for that .
This part is not a reply to the administrator. I AM NOT TRYING TO HACK THE GAME. WAS ONLY TRYING TO PLAY WITH MY FRIENDS ON PLACE WE HAVE, UNFORTUNATELY WE CAN NOT PUT INTERNET YET, WE DO NOT LIVE IN A FIRST WORLD COUNTRY. NOT EVERYTHING IS REASON TO HACK THINGS.
I know it happens, unfortunately, but it happens. BUT THAT'S NOT MY FAULT. >
I'm not trying to create a war or anything like that, just wanted to know if there is any way to change the name in a off-line server, and gave an idea. If this is not part of the plans, OK. This need not become a problem.
