I'm glad to read your post and realize that you are doing your best to manage the application situation at Quinta da Fornalha.
Nevertheless, I would like to reply with my experience.
My name is Ana Teresa and I have previous experience in WWOOFing through the Portuguese network in the last 3 years.
On September 3rd 2012 I wrote a message through the e-mail provided on the contact details on the profile of Quinta da Fornalha. This annual plan that you mentioned was available on the profile already at that time. That is why I analysed it, together with the general description of the farm, and figured out that this was a project that was pretty much going together with what I was looking for. That is why I picked it out of all the more than 100 farms.
On the message I sent (in my name and my partner), we tried to be specific and provide information about ourselves and our experience, according to what we thought was relevant for the case. We also tried to prove to be available to clarify any questions that could help to understand if the matching would be positive and we presented ourselves as flexible and motivated.
There was not any kind of feedback to our application. In the beginning of December we thought it would be fair to try to get any explanation to this (it's also important for a WWOOFer to understand why he/she is or is not picked for a farm/project), that's why after 3 months I made a direct phone call to Quinta da Fornalha, where someone picked the phone and said that it was normal that we didn't get a reply, if we were not selected to be volunteers.
This was my experience with applying to Quinta da Fornalha. This is not a complaint, it's just another point of view.
I hope things go better for you, because there are many people who volunteer with motivation, commitment, will to share and build synergies.
Take care and enjoy,
Ana Teresa Santos
