Do you want tot learn some Russian by Skype? So, I'd like to let you know, that Skype could be very intaractive due to its"Extras". You can share not only your web-cam, or chat with, or call to each other, but also - your display(Oneeko - Extras), that could help you to share your PDF-books and other types of learning materials. I would be glad to spend some time in helping you learning Russian, not only chatting about different things, but real brain-working :)
