my fav language is german, so it will in most situations better, if i can explain my thoughts in my words, but in a chatroom, with almost only english-speaking people, where is the reason to speak german? if i will talk with other elements, i will talk with everybody... not only the german speaking elements...
perhaps i dont understand it right... when im angry and say "scheisse" which means "shit" or "fuck" in english, then i will be warned for not speaking english? i dont think so?!
to cut a long story short: english only!
