How do you find pen pals for people like me who are learning German and think maybe it'd be a good idea to have someone as a pen pal who is a native German?
There is a website of the Ruhr-Universität Bochum where you can easily find a tandem partner for example for email-conversations. This was very useful for me.
You can use a penpal site like http://www.penpalpassport.com to find a language exchange partner. I'm learning English so if you want to practice then I'm happy.
