Anytime I find a very useful tool[1] or get help from a maintainer or author I always offer them a lifetime, free rsync.net account. A fair number of them have taken me up on it.
[1] Some examples of useful tools include: TextBar for OSX, git-annex assistant ... someone wrote a great encfs tutorial ... etc.
That's an awesome way to reward people! I've gotten offers for money, but actually getting to money to me is more of a hassle than it's worth, so I just decline.
Not the OP, but if you run a business, you must be very careful to correctly declare all your income, make sure you invoice properly, pay taxes, etc.
Just because soneone “donates” money, it doesn’t mean that you don’t have to pay taxes.
So in general it only pays off if it is above a threshold. If a company offers to donate 2000€, I would find a way to make it work. But if it’s just a one off donation of 10€, I’d rather not bother my accountant with it.
