You can write me in any of the five languages listed above. Don't hesitate. I just have to admit that my Spanish is elementary. I studied it for three years at school, but it seems like a long, long time. You can send me cards in Spanish, though. Would be a good exercise and a nice change too :) It's a really beautiful language. So far I've just received one card in Spanish. I hope that will change soon.
As for the cards... I'm not too picky. Just send me something you like and that's fine for me. But I must say I've got a little weakness for nouvelles images and cards with pin up girls cards.
What I'm really interested in is what you know about Luxembourg especially if you live far away. I hope you don't mind telling me even if you've never heard of it before. I won't be upset or anything, I promise :)
Oh and if it takes me a while to register your card, don't worry. I'm not home all the time. I spend six months a year in lovely Germany :)
