Players Talking in Other Languages

Now I'm not some lingusitic imperialist, unlike the throngs of Americans who come to London on holiday and are heard commenting on the underground about how we in England refuse to speak 'American', but people chatting away in game chat in other languages makes it a little tricky for the rest of us to know what's going on. Are they making an alliance? Are they calling us all wankers? Are they discussing the latest Dutch porn output? Who knows? It would be nice to know.
