Hi, I'm an old programmer from Brazil. I am 55 years old.
I downloaded your WebCopy software and it is surprisingly very good.
Please answer me this: Do you make sufficient money only with donations?
I am asking you because I would like to make a site like yours with free software made by me and liiving by donations.
The short answer to your question is a resounding no. However it works for others so don't let that dissuade you. Good luck!
