In the past, it has been our habit to post mainly in English. Of course posts in other languages are done and are welcomed by those who can read them, but entire threads devoted to non-English posts have been labeled as such and often translations were included so everyone could enjoy reading them.
There is obviously nothing wrong with some postings in other languages, we are an international lot...but keep in mind that Ertai's points are very valid as well. The majority by far, has English as their common language and the board IS based in an English Speaking country. Non-English posts may not be understood by moderators who must maintain the standards of the forum (ie: watch for use of obscenity, topics unfit for children , insults/flames etc) and cannot do their jobs if they cannot follow an entire thread.
I will say that I do not object to seeing the occasional threads on languages and postings in various languages, myself. It is fascinating to me, but then I studied a few over the years. Having said this, I'm going to add that I would be left out completely from entire threads held exclusively in say- Spanish, French or even German which I have studied a little. You do exclude the bulk of the members by holding an entire thread in another language.
