After one week waiting for a mail from Traveltravel, (I think is fair enough) he/she has not showed up, so If anyone is interested please contact me through my mail juanmadu@hotmail.com, I want to learn Deutsch, (I have basic level) and I can teach spanish (good one, not regional accents) in return, also I speak english so can be a good way to give explanations.
Please seriousness, I was thinking about three-four hours per week using skype or similar tools.
