People have organized groups for centuries- that makes life easier. It was a matter of their own choice if they joined a group of honourable aristocrats of high principles or chose the path of troublemakers and villains.
We are a Polish guild so only Polish-speaking players can be recruited. Min. level is currently 140 and for the players in our academy (Polish Heroes, 45 lvl - recruting 80+) - 115. Enderowo (200 level Ecaflip) is the leader of this guild. The current level is 77, but the guild is still growing.
Our subforum's address is http://forumpd.feen.pl/ - you will find there rules of behaviour an other information on the guild's life (forum is in Polish).
