Born of Hope is a free film that only requires donation. If you like it and you have spare money, then donates it whatever the amount you want to give. That is kind of special, do you not think so? How much do you think this film worth?
I know if a software requires donation, then it is called donateware. After you used the software, price it and give an amount you think what the software may worth. Or, you can use it for free if you are poor, but you need the software, I guess. However, I do not know how can I call this type of donate-film? Place on the Internet and ask donation(s) in the price of your own value?
