This idea just came to me while having to google translate with someone who spoke Hungarian. I talked to him in his language using the translator from Google and it helped him, My idea which Sylar told me to suggest here is to have a script that Auto Detects another Language when it's not English.
Like if someone speaks a they're native language it will show it as English to the English speaking players.
I originally had an idea back then to have a script that does this for every language. Like I can speak english in the main chat talking to another player. and on his screen the text will be in his language that he can understand. (I hope you understand what I mean by this) if not take a look at this example
Using Jim and Vanilla as examples. Jim Speaks Spanish and Vanilla speaks English
On Jim's Screen he see's what he wrote in spanish and see's vanilla's response in spanish
Jim (1): Hola mi nombre es Jim, ?c?mo est?s?
Vanilla (0) Bien gracias
And on Vanilla's Screen, She see's what Jim said in English and writes back in English
Jim (1): Hello My name is Jim How are you?
Vanilla (0): Fine thank you
so hopefully you understand this suggestion, hopefully this can be made and can be useful
Note: Both Sylar and I had the same Idea while discussing this via IRC
