I got to know this guy from the Internet, I'm a Vietnamese living in Germany and learning German; he is a German living in Vietnam and learning Vietnamese. I really want this tandem learning thing to work out for us because, from my side, I want to improve my German skills so much.
I've read some tips for how to make the most of a tandem partnership, but very few of them deals with solely cyber partnership. We obviously won't get to meet in person anytime soon. Therefore, I would like to hear some suggestions as to how to make this situation work out well for both of us?
