I think donations from sales should count. I have sold 2 mid priced machines on here and traded one. I made the recommended donation on each one including the machine I traded, but it didn't get counted toward my account as a donation as my heart turned grey shortly after the sales of the machines. Those three sales should have covered me for at least a year. I was pretty disappointed that it didn't count and I haven't donated since. Now if I sell another machine or something in the future I will make the recommended donation because its the right thing to do, but I do feel it should count as a donation to the site.
