The GROUPs mechanism makes it possible for any language group to communicate with each other in their native language. It would be an idea to point non-English-speaking newcomers towards a group (or groups) speaking their language (where these exist).
Some days ago I started a group where people can post in other languages, not only in English.

Erik. Make a page that people can open up where they can copy text such as when playing a game against someone or a comment in forums and then they can translate it on this seperate page into another language. Also if they wanted to comment in forums but only know russian for example. they can use the translation page to type what they want to say in russian and then translate that back into english so that they can speak in the forums.
Babelfish (http://babelfish.yahoo.com/) is one site that already provides this functionality for free.
