It was in the rules (only English/German allowed) but it was deleted on 6th of may because epvpers is an international Forum. So every language is allowed now. We had the same discussion on here:
Edit:@DrS™: I've no problem with other languages than English/German even if i could not understand them (I only can speak a bit french). The Problem is that the rule existed a long time. No one knewed this was changed. I don't think they have problems with other languages but if you stick to rules a long time and someone change it over night you don't get it recently.
And sorry for Ot, but this had to be said
