Hi Luiz, and welcome!
(Welcome to the rest of you guys, too. 
)
Glad you decided to join us. Don't worry too much about your English, you came across fine.
I'm sure you can tell our little corner of AF is new and growing quickly. Mike and I are working on the FAQ as quickly as we can, and there will be a gallery, how-to's & tutorials coming soon. But don't let our pace slow you down- if you have questions, feel free to ask!
