Pedro Martínez: Thanks for your questions, Pedro.
The WCF uses the word “Federation” as a synonym for “association” or “league.”  Ten years ago, when I formed the WCF, I could just as easily have chosen “World Camelot Association.”
The WCF uses the word “World” because the organization is open for free to anyone anywhere in the world.  Currently, the WCF has members in twelve different countries.  If I can ever manage to publicize the group, my preference would be to have at least one member in every country in the world.
