Doesn't matter where their servers are, or what language you speak. Thanks too forums like these, people of common languages and/or interests will generally post threads and find each other then proceed to stack on particular servers. It's just the social order of things really. I'm not going to go into a bar/club that that has a big heavy metal scene if I am looking for a more mellow country/bluegrass feel.
Life is to short to waste by being nice to everyone all the time. Have fun, **** a few people off, it's good for your blood pressure and peace of mind.
