I have no idea what they actually mean by "European Language" but I assume that includes English.
Actually, the fact that it is called dhost (which seems likely to be short for deutsch host), combined with the fact that most of mainland Europe feels about the same about Britain as they do about us, suggest to me that if you post a website in English there, you can expect it to get wiped. My advice? Give it a shot. But, save a copy of your html somewhere...otherwise you may get a lot more practice typing HTML than you want.
Good luck,

EDIT: Huh. I stand corrected. I guess that they mean that they are not going to allow Asian language sites? I wonder if I could write a whole website in Latin, and then say that it is a European language...a
dead European language, but a European language nevertheless. How about Turkish and Russian? Technically, they are partly in Europe. Do they count?
