I want to volunteer in several different countries. Is there an international membership?
There is no international WWOOF membership. WWOOF is a network of local organisations providing a local and friendly service that speak the local language, know the local volunteer laws and know most of the hosts. By this way WWOOF is able to provide a better service than a centralized website. The exception is the countries that still do not have a National coordination that are listed by WWOOF Independents.
