Until earlier this week, I expected Martin to make a nice amount of money with the development of WinSCP, but then I saw how few people actually make a donation. It's disappointing, to put it mildly.
So I'm calling everyone who uses WinSCP and likes it (and how could you not?) to make that donation. It's only a couple of dollars/euros, so what's stopping you? If it hadn't been for enthusiasts like Martin, we'd all be paying a LOT more for commercial, copy-protected products that may very well be inferior.
So, again, let's keep Martin enthusiastic: let's donate!
