Dan Klumper and Vika: If you would like, I can make my Classroom 2.0 Elluminate account available for your classes to communicate together. Let me know if that would be something fun to do for you both.
That's why it's great to do CLASS projects (like the one Dan Klumper is doing below) so we don't have computers "placing social barriers around students" but the opposite, extending their experience. That is why it helps to have all the kids asking and answering questions like, "How is life like in Russia" and not just one student. It also helps prevent wasting time and an potential for predatory behavior or abuse.
