I don`t want to put more wood in the fire but here it goes:
1- The reason that it as support to English, French and German it`s because they are the languages of the "old status quo".
2- Having or not having a Castellano spoken forum was an option of TRION, good or bad that is another question.
3- In all the south hemisphere the most spoken language is PORTUGUESE (Português) so why not a Portuguese Forum? Although most probably i`m the only portuguese guy playing this game
Ps: Spanish people speak a large pletora of languages but none of them is called spanish, theyr official idiom is Castellano. And they have other languages like Basco, Catalãn, Gallego and at this momment don`t recall more, but there is none called spanish.
