Hey Luiz, not sure about the rest of the world, but we have a few good teams. Some of them you need to pay to get in. For example, Akkari's team, you need probably to attend to their poker school classes that happens in Jaguariuna - SP. I'm curious about this event but it's a bit expensive now, and seems to be to a bit more experienced players than me.
There's also the Mandala Club here in Campinas-SP, but their team is more restrict, you would need to play at their club and if you go well, they will probably invite you.
Some of the options. In my case, I'm in a club with my co-workers ehhehe, we don't have a name, neither play together but we exchange lots of information, reading tips etc..
Nice way to start.
