It would be useful to be able to click 'translate' button on forum.
Then the game would use for example google translate engine to detect languange and translate the message to the default languagle of the player.
If we play on some national server, I do sometimes, on Dutch, French or Russian, but I don't know those languages, it would be much useful to be able to click it and see the message translated, like there is such option on facebook.
It would be faster and easier than to coppy message, open another browser page, go into translator and paste it in.
I dont know how hard it is to implement or if it would use much of server's capacity, but maybe its not that complicated to do. Idea is good I think
