Hi Ine, Thanks for your post. The Hosting Request is a kind of pre-formatted Private Message, so if you have a question or comment you should use Private Message but if you want to request availability from your host than you should use Hosting Request. On both situations your host will receive an email from our system informing that he/she received a message and by using our internal system the host knows immediately that you are a full registered WWOOFer. In the future we will remove the possibility of contact through email, so we encourage the use of Private Messages or Hosting Request.
Wis you a nice WWOOFing,
