Brazilian Portuguese Translation

I’m translating this plugin and I would like to inform to the developers that there are some orthographic mistakes in the English version (the original version).

I would like to collaborate with my Brazilian Portuguese version (over 60% complete). But i found the official translator process to complicated.

I’m still trying to understand how to become a translator, if accomplish it, will be glad in collaborate.
