Hi Renan, welcome!

You'll be pleased to learn that the founder/owner/system administrator/webmaster and all-around "head honcho" of this website is Brazilian. Our own beloved Paulo, aka The Piper. I would not be so bold as to put words in his mouth, but I'm certain he'll be glad to see another fellow-countryman aboard.

As for changing your username, check with one of the Mods. They can do it, or refer it to Paulo who certainly can.

Spread the Faith! Floyd on!
