I'm a veteran player of LOTRO. I play on the unofficial server of the spanish community. We happily coexist with a player base full of Greeks, Italians, Dutch, Finnish, Portuguese, British, Irish, etc. Most, if not all, of the non-english-native players have their own user created channels to freely speak their own language.
We (spanish-speaking players) will also group, play, talk, with any player regarding of their race, language, culture or any other personal stuff.
We are here to play, and just as we embrace anyone as friends, wish to be welcomed (just like anyone else) as guests wherever we go.
I beg you to put away any prejudice you might have about us, because as you know, generalizing is never the smart thing to do.
