And what do you mean about being weird most posts are from new forum members? If these new members took the trouble to create the forum account, it shows the special interest in this topic about translation.
Of course there are costs, or do Brazilian players have free access to expansions? And by any chance, are you going to pay for the translation? As all Brazilians probably bought the expansions, so I think we are entitled to have something with more quality for our community.
To show interest is it necessary to translate the wiki? I think this topic already shows that.
