Learning German and teaching French/English

Hey there, I am a 23 year-old frenchman from Paris. What I like to do in my spare time is judo, skiing, traveling, socializing, play the guitar, fly RC models and finally learning languages. I am looking for someone to regularly exchange in German because I am moving soon to Germany and truly need to refresh my memory. I would rather prefer voice/text chats (eg. skype) to emails, but most importantly someone that corrects my mistakes. I will be glad to teach French or English in return.
