I've just launched iRosetta ( http://www.irosetta.com/ ), a StackExchange powered Q&A site for everything related to language. I'm struggling to get a few key early adopters and thought some hackers here might be interested as most of you are already familiar with the StackOverflow system.
In a nutshell, if you're not sure about a particular translation or have a question about grammar, just ask your question there. If you're a seasoned linguist, get involved and answer some questions!
PS: Suggestions on getting this community off the ground are welcome.
