As for movers and shakers, simple look for the World Conference of Masonic Grand Lodges.
The one in 1999 was actually held in Sao Paulo, when Salim Zugaib, was the Most Worship Grand Master of the State of Sao Paulo, Brazil.
If you go to sites like www.worldfreemasonry.org
you can actually see who attended and spoke about what.
The only thing you need to decipher regarding the info you find and read is which are regular and which are not.
The same as Christianity, Freemasonry has it's spin offs, which claim to be the real thing, and actually are not.
