That's a good idea! I'm from Germany but I went to Portugal to go WWOOFing:

I met lots of interesting people and could check out different lifestyles. If you have a place to spare where you can accommodate people and you need some helping hands in developing your permaculture, you could think about becoming a host. :)
My experiences with them were mostly positive and I remember my time in Portugal quite fondly.

I'm also from Germany and I live here already for about 2 years. It was a good decision to come over. I've heard of WWOOFing. The Permaculture Farm we do most of our shopping have WWOOfers over every now and then. I need to think about it. Having changing people living in the family is somethign you have to commit yourself too.

That's true, you have to feel confident it's the right choice. It's just an option, you do what feels right for you. :)
Best of luck in your lifestyle whichever way you decide to go. I'll keep an eye on your posts.
