[tor-relays] Authority Nodes

Hi,

I see the Authority Nodes are located only in North America and Europe. I would like to contribute to the TOR network as much as possible. I am currently running a node and I would like to make it an Authority Node as well. I am from Brazil and I believe it would possibly be a good idea to have a new Authority Node in South America. What are the requirements? What should I do to become one of them? FYI, the node I am running is 79DFB0E1D79D1306AF03A4B094C55A576989ABD1

Thanks, Vitor Milagres
