We've just launched Arabic and Hebrew language interfaces for Gmail, as well as several new features that will improve the Gmail experience for the people using those interfaces. (You can change the Gmail language interface on the Settings page in your account.)

This was my first project at Google, and I ended up learning a lot about Arabic and Hebrew by talking to native speakers. I'm really pleased to have worked on a launch that will help some of these folks use Gmail and make it available to even more users (we now offer 40 different language interfaces).
