Only, for example, if a friend that is in a specific server, send you a gift in a new FB account that did not start playing T11... then you accept gift and you will start playing on his same server.
I've Bayern in the90ty... 9ty something LOL and the Cheerleaders and the OMA League that I manage between forum members is inside the server 57 too, so thats why I'm thinking that a active market can only work in a same server with some dozens of managers from forum inside... ..I have a group called oficial market of T11 that I created time ago but for the a logic reason it dont works... and is that usually players dont know in what server they are, 1st they have to know server, and then see if there are managers in same... here we are some dozens of active managers everyday in the forum and is strange see more than 2 or 3 in same server (except for the forum league)... then too is more complicated be in same server + same level....
