well, I second that yet I'd love to speak German as you do in the German forums! heheh
Now, from a personal experience point of view; the same idea came up in the Irrlicht forums and didn't work out well since the majority of users with experience spoke English; So once we had someone posting in a certain language there weren't enough users with the required experience to help him sort his problem out. In the end, and by necessity, they ended up asking in English; it wouldn't matter if it wasn't a perfectly "grammared" English; only that they could transmit their question and get someone to orient them in the proper direction. And specially in the case of programming languages, or in this case, an XML script which handles a lot of terms in English. Using English will help understand the format jargon better.
Yet still some specialized forums have been created outside of the official Irrlicht forums: Spanish, Japanese, German, French, etc.
