Zorum is a free software, but it contains many months of our development. Nowadays, we are doing it mostly in our sparetime believing that the result of our work is worth the efforts and you like the program. It is sincerely hoped that you respect the the value of this program and the value of our hard work and help support this site so it can continue to offer and improve Zorum. Please donate as much as you think our service worth. This contribution is purely voluntary on your part. Suggested amount is 10 dollars, though you can donate any amount as you please.
