This question comes up from time to time. I’m not sure if it’s in a FAQ anywhere, but here’s the answer:

Very early on in development I decided not to program Forumwarz in a way that would allow most of the text to be localized easily.

We thought that most of the humour and jokes wouldn’t translate well to other languages, and the extra work involved just wouldn’t be worth it. Also, back then Ruby on Rails didn’t have great support for it.

I don’t really regret it, to be honest. I know it limits our markets, but we are plenty busy already just supporting this one language.

As for advertising in non-US sites, I can see us doing that in the future. Right now we’re still figuring out what ads work and what ones don’t. We’re slowing buying more and more ads each week, and eventually we might try something that isn’t in English.
