I think he means the server on the game. There are 4 different servers, The English Mybrute.com (abbrieviated COM), the French Labrute.fr (Abbrev. FR), the Spanish Elbruto.es (abbrev. ES), and the German Meinbrutalo.de (abbrev. DE)
Since you said you're active on MyBrute, I'm assuming you're level 18 on COM.
