As mentioned, this wouldn't really work in a live text environment where there is a greater amount of spelling and grammatical errors. Machine translations are also bad beyond single words, so I'm not sure that you would be able to have an actual conversation through this.

However, Classic needs to do something that enables non-English speakers to easily find, communicate and play with each other. If I logged into a game where I had to locate an obscure area under a bridge, to simply talk with people of my own language, I don't think I would play for very long. We aren't getting multiple servers (which would be ideal for this) so other avenues need to be explored. I've tried but cannot think of a solution.
