We recently changed the host for our server. As we have another ip, we had to add again the server on Gametracker, but someone else claimed it before we did.

http://www.gametracker.com/server_info/46.4.106.181:25565/

As you can see he's the owner of another community
http://www.gametracker.com/ram_mdy/

here's the links of the past instance of our server, the owner is octyarth
http://www.gametracker.com/server_info/93.119.30.23:25565/

You just need to follow the same steps to claim it. It works in the exact same manner as you did for an unclaimed server.

thanks, i reclaimed it...but what about the one that claimed it the first place?? he posted a note saying the server was moved to his community, that was actually a lie
