@32 that's the point. Since translations are not perfect, it would requires everyone often passing the posts through multiple translators; as many of you out there, I don't want to waste my time doing it, or at least if the forum don't have the facilitie of specifying via a combo box in which language a given user is posting and, related to it, a preference to check in which languages we can read posts. Indeed, if rules depended on me, I would forbid posts written into English with automatic translation; generalize that practice of posting translating by machine entirely not only lacks of courtesy to the rest of the world, but makes understanding posts harder than a poor but human-writen English.
When you say that having people that speak different languages would solve the problem you are being too idealistic. If it is hard to get moderators for English, a language which so many people speak/write with various proficiency but in fact is understandable for many of us, imagine that battle of moderator getting for other languages which, since spoken/written (even with low proficiency) in less countries than English is, there are much less people wanting to take that role or maintaining it for a relatively long time.
Sorry for my bad English. I'm from Argentina and my level speaking this language is low.
