AccountHandler.cs
this line...
private static readonly int MaxAccountsPerIP = Config.Get("Accounts.AccountsPerIp", 2);
change the 2 to 3
not sure about the two other IP's for 6 accounts..... other than making the other 3 with the master account in Game for each IP after the first 3 are made .... not sure if there is a way to script it in.
