I changed the wordpress theme to F2 and to show my appreciation to the author I sent him the pt-br translation files.
However, I think I won’t be using them, since I’m considering maintaining only an English version of this blog. Hopefully it will help me improve my English skills. We’ll see.
If I end up keeping the Portuguese version, I’ll definitely switch the translation plugin from qTranslate to Polylang or WPML. They do a better job handling translations as separate posts, instead of doing some crazy filtering magic like qTranslate.
