That are a handful of reasons to only accept registered volunteers:
One of the conditions all the Hosts accepted when register (on the registration form) is: "I will ensure that WWOOFers are current members of a WWOOF organisation."
WWOOF Portugal is a registered Non Profit Association that lives EXCLUSIVELY from the membership fees. We don't use European funds or Advertisement!
That are only two ways of payment: Bank Transfer and Credit Card (PayPal). In case that happens a serious situation we would give this information to the Police.
We keep registered all the logins, this means the Police could easily track the location and travel pattern of a person.
4- Practical Reasons:
The main problems that happened in Portugal was: A stole car (Range Rover!), a stole Mac computer, a volunteer that locked himself in the host house. This volunteers WASN'T registered!
I think this are reasons enough to only receive registered WWOOFers :wink:
It easy to check (Hosts only)! Login at www.wwoof.pt, click on the WWOOFers tab and type the volunteer name, username or email.
