Both points are good.
And it would be very good if the wwoofers understand that they should write from what day they are available. This is the first year since I joined the wwoof-system asking for wwoof-help (because this year is the first time we rally need help). I got very many negative answers because it seems like most wantsto be here in July or ending of June and I feel like a bulk sender nearly.
Problem is that I am not sure that they read the welcome letter so very carefully. Hope I am wrong.
Some do not write anything in their profile. What do they mean?
Some write that they would like to wwoof. Time : next year! But then they could tell.
Some say it is to far away and want to have possibility to get out of Sweden quickly. Others that it is to far in the north (here) others that they want to be more close to where they are! (they are not moving away for their whole life).
Others say that they have changed their plans so they do not know when they shall travel.
Und so weiter.
These type of answers I got at least three or more of. Some two.
I still do not understand why some ask to come and then I say they are very welcome - no return answer. (probably/maybe bulk-mailing).
In the welcome letter it must be very clear.
"If you want a host to take contact you - write that in your profile and write from what date your are available!"
"If not - write that in your profile!"
"Do not expect a host to take contact to you if you do not write anything."
Something like that could help a little bit. I hope.
